Philips Sonicare 7100: Two-minute review

The Philips Sonicare 7100 isn’t quite as eye-wateringly expensive as the Philips Sonicare 9900 Prestige, but at £350 (around $450 or AU$715) it’s still extremely pricey for a sonic toothbrush with a lithium rechargeable battery that will eventually decay. However, it’s a gorgeous piece of kit with a powerful motor, four brushing modes, three intensities, and a couple of cool accessories such as a charging travel case (downgraded from the Prestige's leather to cheaper plastic) as well as a stand. It's definitely up there with the best electric toothbrushes on our list.

The brush is very satisfying to hold and use. It feels premium: I’m used to very plasticky cheaper electric toothbrushes, so I’m pleased to say that if you're paying all this money, the Philips at least is satisfyingly weighty and incorporates metal into its design. Coupled with the black outer shell, it’s slightly reminiscent of a lightsaber, albeit one that cuts through plaque rather than Sith lords.

At 62,000 bristle motions per minute, the Philips Sonicare 7100 is on a par with the Sonicare 9900 Prestige in terms of its brushing performance. It’s got four brushing modes (Clean, Sensitive, White and Gum Health), and each one has three intensities, for 12 brush settings in total. It’s a case of trial-and-error to find the right one for your brushing routine, and I have a sneaking suspicion that a few of these setting and intensity combinations end up being repeated, based on sound and mouthfeel alone.

However, one thing’s for sure: this toothbrush is powerful. After using my cheaper, lower-powered brush for a while, the blast of the full-power Clean setting on the Philips was surprising, to say the least – a bit like grabbing onto a metal handrail and experiencing a static shock. After prolonged usage, and with the option for such a high-power setting should I want it, I’m not sure I could go back to my comparatively underpowered usual toothbrush.

(Image credit: Future)

The power is evident in the motor, which does emit a moderate whine: using my phone’s decibel meter app, I measured readings of 55-57 decibels, equivalent to a soft conversation. The Ultim8 Supermouth brush, which I’m also testing, measured 44-46 decibels in comparison. The Philips is at the louder end, then, but it’s worth it for that extra oomph.

The battery life – up to three weeks – is largely immaterial, as your brush will likely either be on the charging stand or in the charging travel case most of the time. However, such a good battery life does mean that when you’re caught on the hop – for example, taking your case on long trips – that the brush will hold out and still provide a good clean.

There are only two issues I have with the Philips Sonicare 7100. The first is its price: while it’s an excellent toothbrush, it is more expensive than most in its category, although it does seem to receive frequent discounts. The second is in its name – Sonicare. This is a sonic toothbrush, which is a lot better than a manual brush, but some studies have shown that some oscillating brush heads are marginally more effective at getting rid of plaque than sonic ones. Our guide to sonic vs rotating toothbrushes can tell you more, but the power of the Philips will ensure that with regular proper usage, you’re still getting a great clean.

Philips Sonicare 7100: Specifications Philips Sonicare 7100: Price and availability

(Image credit: Future)

• £349.99 in the UK (around $450 / AU$715)
• Frequently on sale
• The Sonicare Expertclean 7500 is the similar equivalent model in US and Australia
  

The Philips Sonicare 7100 is available in the UK priced at £349.99 (around $450 / AU$715). This is crazy money for a toothbrush, but it’s frequently on sale: at the time of writing, Amazon has it for £158.99 (around $205 / AU$325). I don’t know what it is about electric toothbrushes that means they're priced so highly and then get such severe and almost permanent discounts, but it’s a recognized phenomenon.

Want one in the US or Australia? Philips doesn’t sell the Sonicare 7100 there as it categorizes its products differently in those regions. However, it does sell a very similar Sonicare Expertclean 7500, with four relabelled modes (Clean, White+, Gum Health and Deep Clean) and a slightly differently-shaped charging case. That retails for $199 / AU$312.

If the Sonicare 7100 wasn’t so frequently on sale I’d consider it poor value. However, it should be fairly easy to pick this brush up for around £150-£200, which makes it a very good buy indeed.

Jura J10: two-minute review

If you like elaborate coffees with flavored syrup, the Jura J10 is the fully automatic coffee machine of your dreams – and if you don’t, it might just change your mind.

The J10 also does a great job of the basics, producing consistently rich and well-balanced espresso thanks to a grinder that monitors the consistency of the grind, from which the J10 recommends the optimum temperature and extraction time for each drink (while still letting you tailor the settings to your preferences). The crema isn’t quite as thick and stable as that created by the KitchenAid KF6, but it’s still up there with the best espresso machines – and the J10 has a lot more to offer besides.

In addition, its cold brew option works well as well, and is in fact one of its stand-out features. It uses a different process to the Jura Z10 we reviewed back in 2023. The Z10 also offered a cold brew option, but the J10 works by pulsing water slowly through the grounds rather than forcing it through at high pressure, as you can see in the video below, which the company says should yield a more rounded flavor.

During tests, I found the process delivered a similar flavor profile to traditional overnight cold-brewing methods, taking the bitter notes out of your beans and producing a drink that’s much smoother than one brewed hot. With an ice cube or two to bring down the temperature a bit further, you’d be hard-pressed to differentiate it from the real thing.

The J10 certainly isn’t a cheap option; even if you’re currently placing takeaway coffee orders several times a week, it will take some time for it to pay for itself. Nevertheless, it’s a pleasure to use. The Sweet Foam system isn’t complicated, but it’s implemented perfectly and works exactly as promised. The flavor is distributed evenly throughout the milk rather than being concentrated in the bottom of your cup, so you’ll actually need less syrup for the same intensity of sweetness, and you can use any type of coffee syrup you like, including sugar-free ones.

The J10 does an impressive job of texturizing milk, on a par with the excellent Siemens EQ900 Plus, and with a dose of syrup its foam is even more stable, lasting to the very last drop.

It has a couple of quirks, though. The drip tray is unusually shallow, which means you have to take care not to spill its contents, and the customization menus time out sooner than I’d like. Overall, however, the Jura J10 is a treat to use.

Jura J10: price and availability

• Launched in early 2025
• Priced at £1,795 / AU$3,990 (about $2,300)
• Not yet available in the US, but that may change soon

The Jura J10 launched in early 2025, and is available to buy direct from Jura and from a handful of third-party retailers. It has a list price of £1,795 / AU$3,990 (about $2,300), but at the time of writing (March 2025), it isn't yet available to buy in the US. Other Jura machines are available in the States, so hopefully it will only be a matter of time before it hits those shores.

Jura is charging a premium price for its fully automatic espresso machine then, but it isn't the most expensive around. It comes in less than both the Siemens EQ900 Plus (also a great option for well-extracted espresso paired with perfectly foamed milk) and the KitchenAid KF8 (more stylish to look at, but not so good with dairy).

• Value score: 4/5

Jura J10: specifications Jura J10 review: design

• Hopper for whole beans and ground coffee
• Detects which of its two dispensers you're using
• Sweet Foam system attaches to milk texturizer

The Jura J10 is a smart-looking espresso machine with a glossy piano-black finish. The exterior is made entirely from plastic (even the silver-colored components), which in my opinion isn't a bad thing – the whole machine is easy to wipe clean and isn’t excessively heavy. Some of its rivals weigh over 37.5lb / 17kg, so a machine I can move easily is a refreshing change.

The Jura J10 is an attractive machine, and the company has even considered what its removeable milk system looks like (Image credit: Future)

Unusually for an automatic coffee machine, it has two dispensers: one in the middle for coffee and hot water for espressos and americanos; another on the right for lattes, cappuccinos, and steamed milk, with optional syrup added as the milk is texturized.

There’s a single, generously sized hopper on top, with an airtight seal to keep your beans fresh. Like the KitchenAid Fully Automatic Espresso Machine K8, the Jura J10 also has a chute for adding a scoop of pre-ground coffee, if you want to try something different.

A control dial allows you to adjust the grind size. and the chute lets you add two scoops of ground coffee (Image credit: Future)

Personally, I prefer the twin-hopper setup of the Siemens EQ900 Plus, which can be filled with two different beans at once. Nevertheless, it’s still nice to have an option if you want to switch to decaf in the evening, or have a guest who’s particularly fond of a certain bean or blend.

The J10's water tank is accessed by lifting a flap at the top of the machine and then pulling it out of the side. It’s easy to remove, reinsert, and carry to the tap thanks to a convenient folding handle. The J10 is supplied with a water filter, with a cartridge that pushes onto a plastic adapter and then twists into place in the bottom of the tank to help reduce limescale buildup and remove impurities. Additional filter cartridges are available direct from Jura for $20 / £15.95 / AU$27.90 each.

The J10's water tank is easily removed, and has a replaceable filter to help prevent limescale (Image credit: Future)

The only drawback of the design (and it’s a minor one) is that the drip tray is wide and long, but shallow, which makes it relatively easy to spill the contents while carrying it to the sink. The machine doesn’t warn you until it’s almost full, so I found myself emptying it before I was prompted to avoid getting water on the floor. I did appreciate the spout shape at the back of the tray, though, which makes it easy to pour out the contents when you get it over the sink.

In general, the milk systems of fully automatic coffee makers are quite ugly, often taking the form of open plastic tubs attached to an otherwise stylish machine by a length of slightly medical-looking rubber tubing. This isn't the case with the Jura J10, which has a glass milk container with an airtight lid that’s designed to be stored in the fridge between uses, and which attaches to the machine’s foaming dispenser using a tube with a metal sleeve. It’s a much more stylish solution than most, and works well.

The Sweet Foam system uses a small container of syrup that attaches to the milk texturizer (Image credit: Future)

You do get a plain plastic tube, but this is only used for cleaning the milk system. The Jura J10 comes with a two-part tank that sits on top of the drip tray when it’s time for a deep clean. Just add some cleaning tablets (again, available to buy from Jura), choose the program, and the machine will do the rest, pouring hot water onto the tablets to make a cleaning solution, pumping it through the unit, and depositing the waste water into the smaller section ready to be poured away.

The Sweet Foam system uses a small container that you fill with your preferred syrup (regular or sugar-free), which you attach to the milk foamer. As the steamed milk is dispensed, it becomes infused with syrup, distributing the flavor evenly throughout the milk.

• Design score: 4.5/5

Jura J10 review: performance

• Espresso is consistently well-extracted with rich crema
• Milk is perfectly foamed, and Sweet Foam system works brilliantly
• Cold brew tastes authentically milk and well-rounded

There’s an impressive assortment of presets, including espresso drinks, hot and steamed milk, and hot water. Tap the arrow button above the drink menu and you’ll see a set of extra options including cold brew, extra shot, and Sweet Foam. Select one of these, and you’ll see an icon over the drinks that can be prepared in the way. It’s a smart system that means you don’t have to browse through multiple menus to prepare custom drinks.

As you’d expect with a premium automatic coffee machine, you can also create your own custom beverages, adjusting the temperature, volume, and brew time to suit your preferences. It’s also easy to tweak the machine’s own presets, which is a nice feature that means you can tailor the whole menu to suit your tastebuds – and your cups.

The Jura J10 offers an extensive menu of customizable drink options (Image credit: Future)

I was occasionally frustrated when the customization menus timed out and returned me to the home screen before I’d finished making my choices, but that was the only drawback for me. I just had to be more prepared and not spend time dithering.

When you select a drink, the machine will recommend a grind setting from "mild" to "intense". This is fairly unusual – most fully automatic espresso machines I’ve tested will adjust the grind size for you automatically, and again you’re not given a huge amount of time to do it.

Espresso is delicious, even though the crema isn't quite as thick and stable as that produced by the KitchenAid KF6 (Image credit: Future)

Both dispensers can be easily moved up and down to accommodate different sized cups, and the J10 has a system called Coffee Eye that detects which one your cup is beneath, and only displays beverages that will be dispensed there. It’s a clever addition, and one that eliminates any potential confusion. The machine also has different colored lights that illuminate to show where you’ve placed your cup – white for the espresso dispenser, and amber for the cappuccino dispenser.

The Sweet Foam container lets you control the amount of syrup added to the milk, allowing you to tailor the flavor to your preferences, and you can use any type or flavor you want, including sugar-free. I used a Tate & Lyle coffee syrup provided by Jura; not only were the results delicious, with the flavor distributed much more evenly than it would be if you simply added a pump of syrup to the cup, it also made the foam on my latte macchiato even more stable and long-lasting.

You have to remove and clean the container after each use, but this doesn't require much effort. Having the syrup in some sort of tank inside the machine for use on-demand would mean the machine would need another type of cleaning cycle to wash out the sugar, and you’d be limited to one type of syrup at a time.

In the J10's setup, the syrup doesn’t enter the rest of the milk system at all, so there’s no sugar in the machine to act as a breeding ground for bacteria. Plus, you can use a different flavor whenever you feel like it. I washed the container by hand, which took only a moment, and Jura recommends popping it in the dishwasher once a week for a deeper clean.

I was particularly interested to try the cold brew option, which promises authentic-tasting cold coffee drinks in moments, with the same flavor profile as cold brew that's been extracted in the traditional way over the course of many hours. Cold brew does take longer to dispense than a shot of hot espresso, but not by much – it drips from the dispenser, rather than issuing in a stream – and the taste is very impressive. It might not be quite as flavorsome as authentic cold brew, but it’s very close; it's sweeter, with far less bitterness than espresso brewed hot. Throw in some ice and I think you’d be hard-pressed to tell the difference.

The Jura J10 comes with a two-part tank for deep-cleaning the milk system (Image credit: Future)

Like any fully automatic coffee maker, the Jura J10 requires regular cleaning to keep it hygienic and ready to brew. One feature I particularly appreciated was its ability to run a rinsing cycle automatically when it hasn't been used for a certain period of time. This is something I’ve only previously seen on commercial bean-to-cup machines, and it makes a lot of sense. You can tinker with the cleaning and maintenance settings (including rinsing) by tapping the small arrow button on the bottom of the coffee menu.

• Performance score: 5/5

Should you buy the Jura J10 Buy it if

You enjoy decadent coffee drinks

The Jura J10 lets you replicate even complicated coffee orders at home, and gives much better results than just adding a pump of syrup to your cup.

You enjoy cold brew

The J10's updated cold brewing system is fast and effective, producing a flavor profile strikingly similar to coffee brewed cold overnight.

Don't buy it if

You prefer traditional coffees

If syrup and cold brew aren't your thing, you can get excellent results from a more affordable machine such as the standard Siemens EQ900.

You're a bit clumsy

The wide and shallow drip tray can be prone to spilling if you're not careful, and the J10 won't warn you until it's very full.

• Cortical Labs has built the first deployable biological computer, priced at $35,000
• The CL1 integrates living neurons with silicon for real-time computation
• The next step will be to build a biological neural network server stack

Despite the unquestionably impressive advancements we’ve witnessed in recent years, AI is still lagging far behind human intelligence. While it can process vast amounts of data, recognize patterns, and generate responses at speed, it lacks true understanding and reasoning, and although it’s getting better, the issue of hallucinations - when the AI makes stuff up - remains a problem.

Two years ago, researchers from Johns Hopkins University in Australia, together with scientists at Cortical Labs in Melbourne, suggested that the answer to real, less artificial AI was organoids - computers built with human brain cells. Fast forward to today, and Cortical Labs has turned the theory into reality with the production of the world’s first commercialized biological computer.

The CL1, which will be manufactured to order but is available for purchase online (the option to buy time on the chips will also be offered), is a Synthetic Biological Intelligence (SBI).

Connecting directly to neurons

“Real neurons are cultivated inside a nutrient-rich solution, supplying them with everything they need to be healthy. They grow across a silicon chip, which sends and receives electrical impulses into the neural structure," the company says.

The world the neurons exist in is created by Cortical Labs’ Biological Intelligence Operating System (biOS) and “runs a simulated world and sends information directly to the neurons about their environment. As the neurons react, their impulses affect their simulated world. We bring these neurons to life, and integrate them into the biOS with a mixture of hard silicon and soft tissue. You get to connect directly to these neurons.”

By deploying code directly to the real neurons, the company claims the CL1 can solve today’s most difficult challenges, “The neuron is self-programming, infinitely flexible, and the result of four billion years of evolution. What digital AI models spend tremendous resources trying to emulate, we begin with.”

"Today is the culmination of a vision that has powered Cortical Labs for almost six years," noted Dr. Hon Weng Chong, Founder and CEO of Cortical Labs. "However, our long-term mission has been to democratize this technology, making it accessible to researchers without specialized hardware and software. The CL1 is the realization of that mission. While today's announcement is incredibly exciting, it's the foundation for the next stage of innovation. The real impact and the real implications will come from every researcher, academic, or innovator that builds on top of it."

A report from New Atlasclaims Cortical is constructing a “first-of-its-kind biological neural network server stack, housing 30 individual units that each contain the cells on their electrode array, which is expected to go online in the coming months.” The site reports the company is aiming to have four stacks available for commercial use via a cloud system by the end of 2025.

As for pricing, the CL1 will be surprisingly affordable. “The units themselves are expected to have a price tag of around US$35,000, to start with (anything close to this kind of tech is currently priced at €80,000, or nearly US$85,000),” New Atlas adds.

For context, Apple’s “best failure” the Lisa, which paved the way for the Macintosh and even Microsoft Windows, sold for $9,995.00 in January 1983 which, adjusting for inflation, works out to a comparable $32,500 today. Will the CL1 prove be as important to computing’s future as the Lisa was? It's impossible to say, but for now its impact will largely depend on scalability, practical applications, and how well it integrates into existing AI and computing systems.
