[This review was collected as part of a promotion.] I cannot believe I waited this long to use an electric toothbrush. My teeth feel as clean as the day I visit the dentist. The toothbrush is easy to travel with and the app is very useful. Glad I purchased it.

We had this same toothbrush for the past 3 years and liked it so much, we bought it once again. The All in One brush heads are pretty amazing.

[This review was collected as part of a promotion.] This is the best electric toothbrush I've used! I love the 14 day “warm up” period so that it doesn't feel too harsh right away. The buzzing between zones helps make sure you brush each section for the correct amount of time and after using this toothbrush my teeth feel almost like I've just walked out of the dentist. Super happy teeth! I received this electric toothbrush from the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] From the moment I opened the box, I knew this was going to be a game changer for my oral health and cleaning. The Philips Sonicare DiamondClean Smart toothbrush, not only looks sleek but it gives my mouth a cleaning I never thought I could possibly do on my own. The first thing I did was download and connect the app, this allowed me to pair it with the toothbrush and identify that I wanted to start with the whitening program. There are 4 different modes to choose from. It was great that the toothbrush already had a charge so I could use it right away. When I started the program it guided my through my brushing identifying where I needed to place the brush and the really neat thing was that it notified me by a pulse if I was pushing too hard or scrubbing. It also gives you a little pulse to tell you to move onto the next section of teeth. I don't think my mouth has ever felt this clean, and clean for hour following brushing my teeth as well, as it has from using this toothbrush. One of the great features is that there is sensitivity settings, so I felt comfortable cleaning my teeth and gums, this is definitely something that makes this toothbrush stand out from the rest. I've noticed that this toothbrush has set me forward on a great oral health path, not only by providing an amazing brush, but giving me reminders to floss and clean my tongue. My oral care routine feels incredibly thorough now that I have started using this. My favourite feature has got to be the cleaning indicator on the app that pairs with the toothbrush, I feel totally confident I hit all the right spots when I follow along with it. This toothbrush gets a very thorough and clean 5 stars from me, I can't stop raving about it to everyone I talk to. Very grateful Stellar Product Testing Panel sent me this product to try.

[This review was collected as part of a promotion.] I've had the DiamondClean 9350 for a few weeks now and I'm really happy with it. The first thing I noticed is just how much cleaner my teeth feel compared to using a manual toothbrush, it's a noticeable difference right away. It's also a very attractive, sleek toothbrush that doesn't look like clutter on the counter. While it comes packed with multiple settings, intensity levels, and specs for people who want to customize every detail, I generally stick to one mode and it works perfectly. Simple to use, high quality, and does the job really well. Overall, it's just a solid, high-quality product with zero complaints. If you're looking for a dependable upgrade to your daily routine, this is a great pick! I was given this electric toothbrush to try as part of the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] Received as part of the Stellar product test panel. All I can say is wow! I already had a handheld sonicare pulsing toothbrush and thought - how much better could this one be? Boy was I wrong! With the different cleaning modes, detection for when you press too hard, and just overall power in this brush my teeth have honestly never felt cleaner. In just a couple weeks my oral health feels completely better and I can't stop telling people about this toothbrush !!

[This review was collected as part of a promotion.] I received this electric toothbrush from the Stellar Product Testing Panel, and I was very excited to try it out because despite having used a few different electric toothbrushes over the past decade, I have never owned a Sonicare. First impressions taking the toothbrush out of the box, was how beautiful the toothbrush looks, as well as the number of high tech features and accessories it came with. The portable charging case is so useful and keeps everything in one compact place when you're on the go. No more settling for manual toothbrushes when traveling! After my first brush, I was blown away by the cleaning performance which was noticeably better than all the previous toothbrushes I've owned. It's almost unbelievably clean! My previous electric toothbrush had a rotating head which would clean the surfaces of my teeth very well but often left a lot of plaque on the gumlines. The Sonicare on the other hand gets into all those little crevices. The All-in-One brush head that comes with the toothbrush set is especially good, and I find that its wider brush profile allows it to have broader surface coverage and better reach to my back molars. It's been so effective that I've noticed a reduction in the time I need to spend flossing! The pairing function which remembers each brush head's preferred settings is great, and makes sharing the toothbrush handle with my husband so easy. It's helpful because there are so many different cleaning modes and intensities! I love the deep clean mode and despite using it on the lowest intensity, it is sufficiently powerful and thoroughly cleans my teeth without irritating the gums. My teeth are so smooth and clean that I can't stop licking them! One feature I do wish it had is a method to visually differentiate identical brush heads. Having something like coloured ring attachments or designated storage slots would make it easier to share the toothbrush handle. Not a dealbreaker though, and I am overall very happy with the product as well as my improved oral health. Definitely won't be going back to my previous toothbrush any time soon!

[This review was collected as part of a promotion.] I love the DiamondClean Smart rechargeable toothbrush. I am disappointed in the longevity. This is the second one I've bought in just a couple of years. I've used Sonic for as long as I can remember and they typically last a very long time but not this one. Giving it one more chance but if it doesn't last, I won;t buy another one.

[This review was collected as part of a promotion.] I received this toothbrush as part of a Stellar Product Testing Panel, and I am so grateful to have been chosen! Upon first use, I was immediately struck by the power of this electric toothbrush—it felt as though I was having a cleaning with my dental hygienist, but without the awkward saliva sucker and in the comfort of my own home! While the toothbrush is very powerful, it is also gentle. At no point in the brushing experience did I find sensations overwhelming or unpleasant. After the first brush, I was struck by how clean my teeth felt in comparison to when I brush with other electric toothbrushes. After a few uses, my teeth were noticeably whiter, and it even cleared plaque from between my crowded teeth in a way that I struggle to achieve without intensive flossing. I love how customizable the settings on this brush are. The four modes and three intensities really allow the user to have exactly the brushing experience they need at any given time. I loved the deep clean mode for after meals that included corn on the cob, as it really cleared away the residual bits stuck in my teeth without the need for flossing. From a practicality perspective, I also loved that the travel case comes with a built-in charging cable! It's so nice to not have to remember to pack a charger when we're away from home. I may actually use the case to charge at home, too, as the one element I was not as fond of was the unique charger the brush comes with. The base comes with two attachments to hold the brush: one of them is just a plastic disk with a spot for the brush to stand upright, and the other is a water glass that attaches to the charging base that you can pop your brush into to charge. While the latter is undeniably chic and would look great in many bathrooms (and be useful, if you like to follow up brushing with a rinse of water!), neither attachment held very securely to the charging base. And in my tiny bathroom, with no real counter space and rambunctious small children, this was not an ideal charging set up. That said, it looks and works phenomenally well, if your bathroom and lifestyle is more amenable to such things! Over all, I would heartily recommend this toothbrush to anyone! I feel it has made a huge difference in my oral health, even in the short period of time I've been using it.

[This review was collected as part of a promotion.] I was given this electric toothbrush to try as part of the Stellar Product Testing Panel. I really enjoy using this toothbrush and my teeth have never felt cleaner! My old Philips electric toothbrush was 10 years old and barely held a charge for a few days. The realtime brushing guidance with the Sonicare App is what made the biggest difference in my brushing routine. Having a visual of where I needed to brush and how much time I had left before needing to move on to the next section helped me achieve thorough brushing while being efficient. Being able to see stats on brushing steaks, flossing, tongue cleaning, mouth rinse, frequency and duration of brush times keeps me accountable and motivated to brush my teeth. I found it very satisfying to continue my brushing streak. Another feature of this toothbrush that I appreciate are the pressure sensors and notifications if I was “scrubbing”, greatly reducing two habits that I am guilty of. Of the four modes, I enjoy using “clean” as my daily mode and “gum health” every 3-4 days. Compared to my old toothbrush, I am able to differentiate the differences between these modes in both pressure and timing. Especially when paired with the app. The toothbrush has a sleek design and looks great on my countertop with the charging glass. It comes with a charging travel case that can carry two heads. This is convenient when travelling with my husband – we only need to bring one base between the two of use and don't have to pack a separate charger. However, I dislike that the charger is a USB-A charger. A USB-C would be more convenient as all my electronics use USB-C charging bricks. While it is a great toothbrush, I would recommend the Philips DiamondClean to people who are interested in an using the app along with the toothbrush to maximize the benefits of the toothbrush.
