[This review was collected as part of a promotion.] Thank you to Stellar Product Testing Panel and Philips Sonicare for sending me thePhilips Sonicare DiamondClean Smart 9350 toothbrush for free in exchange for my review. I've been a loyal sonicare user for many years and was excited for this opportunity as my last toothbrush recently stopped working (wonderful timing). I've been using a manual toothbrush for the last month or so and after using the Sonicare again I noticed white and cleaner feeling teeth. My mouth felt cleaner as well. I appreciate the four different modes ( deep clean and whitening are used most often) and the three intensity levels (I use level 2). As I am a heavy brisher in regards to pressure, having the pressure sensor is very beneficial to me. I love the brushing app as well,.it gives me reminders and tacks my brushing habits!

[This review was collected as part of a promotion.] So this is my second set of brushes! The first lasted well over five years and the only reason that I am on the second set is I wanted the new set with more features. The brushes are the best on the market, in my opinion. The clean feeling you get after brushing is as if just went to your dentist. Great product!! Highly recommend!!

[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 like the toothbrush but not the brushing sequence on it. I brush bottom left to bottom right then top right to top left but the app sequence is opposite. I had another Philips toothbrush but it was close to its life ending. So this one that I bought is a higher rated one an I just bought it recently.

[This review was collected as part of a promotion.] I had never used an electric toothbrush before, largely because I was hesitant about the cost and wondered how much better it could be than the free toothbrushes from my dentist. The difference, however, has been remarkable. Thanks to the Stellar Product Testing Panel for providing me with this electric toothbrush. The first few days required some adjustment, but I immediately noticed how clean my teeth felt after brushing. Although the sensation took time to get used to—and the sound bothers my dog—the results have been clear: I find less debris between my teeth when flossing, and at a dental appointment about a week after I started using it, my dentist noted that I had significantly less plaque than usual. I look forward to seeing the long-term difference between cleanings. After trying every setting, I settled on whitening mode because it best supports my current dental goals; a friend even asked whether I had been using a teeth whitener. The toothbrush looks sleek, and I genuinely look forward to using it. I was initially concerned that I might brush too hard or move too quickly, but its guidance on pacing and pressure is clear and easy to follow.

[This review was collected as part of a promotion.] I received this toothbrush as part of the Stellar Product Testing Panel and I am absolutely in love with it. From the first use my teeth felt noticeably cleaner, like I had just left the dentist. I was amazed by how gentle it was while still doing a remarkable job. As someone with a couple decades and thousands of dollars worth of orthodontic work I take oral hygiene pretty seriously and tend to be a bit of a toothbrush snob and this thing checked all the boxes for me. The quad pacer timer helps tremendously because I tend to struggle with focus and it reminds me to switch to a different area. I was worried the timer would make it feel like brushing was taking way too long but I have found the opposite to be true because it interrupts my zoning out so I think it has actually decreased my brushing time while simultaneously greatly increasing the effectiveness of it. At a recent dental appointment I was told by the hygienist that my teeth were "boring" because I didn't leave much for her to do (scaling etc). It may have been the shortest appointment I have ever had which is a definite win in my book.
