Diamond Clean Smart 9350- Ideal

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.

Philips Sonicare cannot be beat

I received the Philips Sonicare Diamondcare Smart 9350 toothbrush from the Stellar Product Testing Panel to provide my honest feedback about the product. I have to say I was a bit skeptical at first when using this device as I had used some electronic toothbrushes in the past and was not satisfied with them. I always found myself going back to my manual toothbrush to get that feeling of actually scrubbing my teeth. After learning about the pressure sensor on the brush and the app integration I decided to give it a try. I was immediately impressed with the power on the brush and found it strong to clean but not too strong that it was hurting my gums. The brush vibrates to tell you when to switch to a new cleaning zone during your session which is great to make sure you're spending enough time on each spot. The pressure sensor is something that was a game changer for me. There is a vibration and a light if you use too much pressure. I believe my issue with electric toothbrushes before was that I was actually using too much pressure. Once I found the sweet spot for how much pressure to use I couldn't believe how clean my teeth felt after brushing. Through the Sonicare app I also found out I was scrubbing too much and just needed to let the brush do all the work. I also love that in the app it tracks exactly where you have brushed in live time so you can make sure to get the perfect result everytime. Overall I really like this product and would recommend it to anyone interested in trying an electric toothbrush. With all of it's features it makes to so easy for anyone to try it for the first time and get the perfect brush.

My teeth feel SO smooth

I have had electric toothbrushes in the past - from several different brands - and this Philips Sonicare DiamondClean had some very cool features I haven't seen before. Here's what I liked: USB charging travel case - makes life SO easy on the road - it's so nice that our phones, and electronics have consistent chargers these days - and makes it so easy if you forget the charger too! I have never had a toothbrush with an app before - an app that gives you an idea of how well you are brushing, helping you make sure you get to all of the different nooks and crannies of your mouth, as well as with reminders to book dentist appointments. The app has been pretty straightforward to use and I haven't had any issues syncing the toothbrush. The charger is very stylish and looks nice on my bathroom counter - It just looks like your toothbrush is in a small glass - very cool. But my favourite feature is the pressure sensor on the bottom that glows purple if you push too hard. My 9 year old loves calling me out and telling me that I am pushing too hard! It seems counterintuitive - like if you're brushing your teeth "well" you should push hard - but when you have an ultrasonic toothbrush, you don't need to - and your gums will thank you for it. On to the one con I can think of - the price is on the higher end - BUT - teeth are expensive to fix, and we need to take care of them - perhaps having a toothbrush that does a really good job of keeping them clean is a wise investment? Also your oral health can impact your physical health - so having a good toothbrush and consistent routine is very important! I have played around with the different cleaning settings and intensity options and usually just stick to the basic clean setting. So far so good - my teeth feel nice and smooth, my breath has been good, and my brushing habits have improved thanks to the app! I will probably go buy one for my husband! Thanks to the Stellar Product Testing Panel fro providing me with this electric toothbrush.
