[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.] I received this toothbrush to review through the Stellar testing panel and I'm so glad I did! I feel like I've been to the dentist when I use it; my teeth feel amazing. One feature I really love is that it lights up if you press too hard. I didn't realize I was too aggressive with my teeth brushing until I used this toothbrush and have adjusted my technique.

[This review was collected as part of a promotion.] I received this electric toothbrush the Stellar Product Testing Panel. I've been using an electric toothbrush for the last 3 years and this one is hands down the best. What stood out immediately was how sleek and streamlined it looks- it's the first toothbrush that I leave sitting on my vanity because it actually looks nice. After the first brush, I noticed that my teeth felt cleaner and my gums felt less irritated than they had with other toothbrushes. I appreciated the four cleaning modes but mostly stuck to the whitening setting and the lowest intensity mode. The compact charging case and glass charging base are great additions that previous models haven't had! The battery life is great, and I achieve clean, white, fresh teeth every brush! Thank you Stellar Product Panel Testing for this opportunity, if you're looking for an electric toothbrush this should be at the top of your list!

[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 received the Philips Sonicare DiamondClean Smart 9350 through the Stellar Product Testing Panel, and I've really enjoyed using it. After the first few brushes, the biggest thing I noticed was how clean and smooth my teeth felt compared to my previous toothbrush. I also like having different modes and intensity settings depending on how my mouth is feeling that day. The pressure sensor is especially helpful because it lets me know if I'm brushing too hard, and I find it reassuring that I can get a thorough clean without being too harsh on my gums. The feature that has made the biggest difference for me is probably the pressure sensor and overall brushing experience. It makes brushing feel more effective while still being gentle, and I like that the toothbrush does a lot of the work for you. Overall, it feels like a nice upgrade from my previous electric toothbrush.

[This review was collected as part of a promotion.] I was given this toothbrush as part of the Stellar Review Testing Panel. I have used Sonicare electric brushes for a long time and have always appreciated their durability, effectiveness and ease of use. This version is totally worth the upgrade. My family all use the same brush with different heads, and the fact that this brush maintains the preferred settings, based in the brush head is amazing. I also appreciate the app, especially for my kids to get a sense of correct brushing techniques, as well as for a check in for the adults! My mouth feels cleaner, the process is fully customizable to what each person needs (gum health, whitening, gentle, etc.), and it also looks nice in the counter. This brush really is awesome.

[This review was collected as part of a promotion.] I will say first that I received this toothbrush as part of a review from the stellar product testing panel, but that aside, I love this toothbrush. I previously had a Phillips Sonicare toothbrush, and this was an upgrade. I have been using it for about 3 weeks, as I wanted to be able to give a solid review. Twice daily, as you do. I've been using the copper colored brush head. And I will say it has actually made a difference. I love the app compatibility, it makes it easy to follow and make sure you're both distractedly missing anywhere. I do feel like my teeth FEEL better. Like post dentist smooth. I would absolutely recommend this tooth brush, the pressure sensor and movement sensor actually are super helpful. The biggest downside is the price. It's steep for a toothbrush. I do think that if you're a person who goes a little longer than they should between cleanings, that investing in this toothbrush is probably worth it though. Overall, I truly do love this toothbrush.

[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 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 find a noticeable clean with my Philips Sonicare DiamondClean Smart 9350 Rechargeable Electric Toothbrush. My teeth actually feel cleaner. I enjoy that it has a timer for when to move on to the next section for cleaning so I don't skip out on any cleaning time. I didn't use the app but I do love that this toothbrush comes with a charging travel case. I was given this electric toothbrush to try as part of the Stellar Product Testing Panel.
