[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with the Philips Sonicare DiamondClean Smart 9350 Rechargeable Electric Toothbrush to try. I've been using Philips Sonicare toothbrushes for about 17 years, so I was excited to see how this model compared to my previous ones. Overall, I REALLY like the toothbrush, particularly the pressure sensor, Deep Clean and Whitening modes. After using these settings a few times, my teeth looked visibly whiter and my mouth felt noticeably cleaner. That said, not every feature feels necessary, but they are nice. The glass charging cup is nice-looking, but I found it a little gimmicky. It would be great to be able to use older model chargers as well. My husband has a different model, and now we are using separate chargers. Overall, I like the DiamondClean Smart 9350 and will continue to use it. However, I'm not sure I would spend the money to purchase this particular model myself. I was completely happy with my previous Philips Sonicare toothbrushes, which provided a great clean without all of the additional features and higher price tag. Overall, it's a great toothbrush with truly noticeable whitening and cleaning results, but whether it's worth the upgrade will depend on how much you value the extra features.

[This review was collected as part of a promotion.] Our family currently uses a lower-tiered model Philips Sonicare prior to receiving this one. It was a pleasant surprise to get this to compare with. I was given this electric toothbrush to try as part of the Stellar Product Testing Panel. Upon first use, there is a big difference in the vibration and noise. The Philips Sonicare DiamondClean 9350 is significantly quieter than our lower tiered model and the vibration is much less pronounced in our hands. Previously, we could clearly hear each other outside the bathroom walls if we were brushing our teeth. Now it is much less pronounced. This is definitely a great benefit as someone who gets up early to work while the rest of the family is sleeping. Another feature we found useful was the light ring accompanying the pressure sensor. I have been advised by my dentists that I brush quite heavily. I felt that the DiamondClean 9350 is more sensitive than other models, with the light ring providing a great visual cue to lighten off. This was very useful! For our lower model, a vibration accompanies the pressure sensor but is easily missed. The visual cue with the light ring is very helpful! The Sonicare DiamondClean 9350 comes with a plethora of insights and guides with the Philips Sonicare app. This was interesting to go through within the first few uses. However, we felt there was no further added value after the first few uses. I felt this was more of a gimmick and would rather consult my dentist or dental hygienist for more personalized guidance and tips. This was a great upgrade to our existing model. With the features I've mentioned, it is definitely some quality of life improvements for us. However, with the price differential of the DiamondClean 9350, it is not something I'm willing to pay a large premium for. Amazing device that improves quality of life if you are willing to pay for it.

[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.] Thanks to the Stellar Product Testing Panel for providing me with this electric toothbrush. Before receiving this toothbrush I was using either a manual toothbrush or the most frugal version of electric toothbrushes. My husband swears by electric toothbrushes and so it was interesting to put this one to the test! It did not disappoint, it was definitely like a zero to 250 feeling - after the first brushing my teeth felt cleaner than they do after a cleaning at the dentist. I was surprised at the great job the brush did at not only making my mouth feel clean but my teeth look brighter and more white, just using the toothbrush and my usual toothpaste. I've tried 3/4 of the modes (1 week at a time to genuinely test) and I can actually tell the difference. I definitely had to use the lowest intensity setting because it's something to get used to after using such simple toothbrushes. It takes some getting used to because you only have to hold the toothbrush on your teeth, no scrubbing or brushing up and down required. I appreciate the gum health setting the most followed by the White+ option. The feedback provided by the Sonicare app is next level and it will tell you if you've missed an area in your mouth! I do wish you could tack on an extended session even after completing a full brushing. I was tickled by the glass it comes with that allows you to charge the toothbrush. I feel like I've joined the fancy toothbrush club.

[This review was collected as part of a promotion.] Between running a busy house with two kids and keeping up with a full-time job, my morning routine needs to be completely foolproof. When I received this Philips Sonicare toothbrush from Stellar Product Testing Panel and was asked to share an honest review, I was all in—and it genuinely delivers. The real magic is in the specialized toothbrush heads; they actually do what they promise, and the handle automatically syncs to the right mode the second you click one on, taking all the guesswork out when you're running on coffee and pure adrenaline. It leaves my teeth feeling as ridiculously clean as if I just left a dentist's chair, all in two minutes flat. Sure, it's definitely a splurge—so keep an eye out for sales and bundle deals—and while it comes with a fancy smartphone app, nobody has time for that while packing lunches; you can safely skip the app altogether and still get every single benefit. For a quick, effortless win in the middle of everyday chaos, it is worth every single penny.

[This review was collected as part of a promotion.] I got this toothbrush through the Stellar Product Testing Panel, and I LOVE IT. I was already using a different model of Phillips Sonicare toothbrush, and my dentist always compliments me for flossing my teeth, even though I don't. So needless to say I think it's a great product. But the DiamondClean model is even better. Feels like I've just been to the dental hygienist after every brush. I've been using it on the whitening setting, and I was skeptical that it would make any difference, but I think it has specifically improved some coffee staining happening to a porcelain tooth that I have. All in all this is a great product, and I will buy again and get one for my husband.

[This review was collected as part of a promotion.] I received the Philips Sonicare DiamondClean Smart 9350 through the Stellar Product Testing Panel, and I absolutely love it. My teeth have never felt so clean after brushing! One of my favourite features is the app. It shows me exactly where I've brushed and highlights any areas I may have missed, which has made me much more aware of how thoroughly I'm brushing. The built-in timer and prompts are also really helpful, taking the guesswork out of making sure I'm brushing properly. I also really appreciate the different brushing modes and intensity settings. I have a few areas where my gums can be sensitive, so being able to adjust the settings depending on what feels comfortable has been perfect. It still leaves my teeth feeling incredibly clean without being too harsh on sensitive areas. Overall, this toothbrush has made a noticeable difference in my brushing routine. It feels like I'm getting a much more thorough clean at home, and the smart features are genuinely useful rather than just extras. I would certainly recommend it!

[This review was collected as part of a promotion.] I received the Philips Sonicare DiamondClean Smart 9350 from Stellar Panel to test and review, and after using it, I have some features I really like as well as a few areas that I think could be improved. The toothbrush is aesthetically appealing, and I really like the matte finish, which makes the brush comfortable and nice to hold. After using it for the first few brushes, the Deep Clean feature stood out to me the most. It gives me the feeling that I'm getting a more thorough clean, especially around the gumline. I noticed that my teeth feel significantly cleaner after using the Deep Clean mode compared with the regular Clean mode. I also like having four different modes and three intensity settings, as they allow you to customize the brushing experience. Even with the stronger settings, the toothbrush still feels gentle on my gums while providing a thorough clean. The pressure sensor is another feature I appreciate because it helps ensure you aren't brushing too aggressively. I haven't had a recent dental checkup, so I can't say whether my dentist has noticed any improvements. However, I can personally tell a difference in how my teeth feel when I use the Deep Clean feature. My teeth feel noticeably cleaner and fresher afterward. With the other modes, I don't notice much of a difference compared with my older Sonicare electric toothbrush. One feature I'm not a fan of is the charging system. I find the glass charging cup unnecessary and feel that it takes up extra counter space while also being another item to clean and maintain. I actually prefer the original Sonicare charging dock and think a glass cup is unnecessary for charging the toothbrush. That being said, I really like the travel case with charging capability. It's a feature I appreciate and think is a great addition compared with other Sonicare models. Overall, I think the DiamondClean Smart 9350 is a sleek, comfortable toothbrush that provides an especially impressive clean with the Deep Clean feature. The charging cup isn't my favourite design choice, but the cleaning performance and charging travel case are definite positives.

[This review was collected as part of a promotion.] I was so excited to get this toothbrush as part of the Stellar Product Testing Panel, and it delivered! I used an older Philips Sonicare toothbrush before trying this one and this new one has great new features! First, I love that the travel case recharges my toothbrush so I don't have to bring the cord and stand when I travel anymore. Second, the 4 settings on the toothbrush are also super helpful so I can choose which setting I want for different needs. I especially love the Deep Clean setting when I just want a little more. Overall, my mouth feels perfectly clean after every use. One thing that I noticed is that the vibrating is more intense than my previous model. That said, I got used to it really quick (after a couple uses) and now I don't even notice the increased intensity.

[This review was collected as part of a promotion.] I've been using this toothbrush over the past three weeks. I really like the squeaky clean feeling after brushing my teeth, more so than with other electric toothbrushes I've used in the past. I also really like how it looks on the counter with the glass charging cup, and the travel case with built in charger is great! Not sure about the app. The app will let you know where you are scrubbing too much, pressing too hard or missing part of your teeth. Sometimes the app can be glitchy and if you don't start brushing with the app open it won't register that you're brushing at all. I find that on the basic setting, I want to brush my teeth more often and used my toothbrush twice a day consistently. Before I might have brushed with an “analog” toothbrush in the morning and then used the electric toothbrush during the evening. I don't find I use the gum or whitening modes much, as they feel very long and I don't notice a difference to my teeth from the regular mode. I received this toothbrush as part of an incentive program (Stellar Product Testing Panel).
