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.

I cant wait to hear what my dentist has to say
What a difference, my gums felt better overnight. You know how when you start flossing more regularly it takes a while to feel better? Not the case here, it was pretty much instant. I usually get caught in a cycle of not liking how clean my teeth feel, then over brushing with a manual brush, then gum irritation but I loooooved the transition to using the Sonicare. Clean clean “just back from the dentist” polished feeling and happy gums. There are multiple intensity settings and I’m still on the most gentle one a few weeks in, I’m so happy with how the brush cleans and how my gums feel that I haven’t needed to progress any higher yet. There are also multiple cleaning settings, my favourite is the gum health setting. My teeth are seriously sparkling all the time and my gums look SO healthy (and I still forget to floss some days…) it’s such a confidence boost. I have a wire retainer on my lower front teeth that I’ve had for years, the Sonicare toothbrush makes short work of cleaning it. I still do the whole thread flossing thing still but it’s been effortlessly clean it really takes a mental weight off. I know the brush is doing a darn good job by itself already because I can feel it, and I don’t feel like I have to do a bunch of catch up with the floss for the spots I’ve missed because there aren’t any, I can just focus on the gumline. The pressure sensor is so cool, I was really pleased with myself that it didn’t go off lol. BUT with the app integration I quickly learned I still scrub. WHAT! I had no idea. You’d think looking at yourself in the mirror you’d know you’re scrubbing your teeth but nope - I guess the muscle memory of learning with a manual brush thirty years ago kind of takes over. Huh. That was a surprise. Easy to fix too, the app is super fun to follow along and it tells you if you might have missed any areas along with it you scrubbed or applied too much pressure. Very cool! And you don’t even need the app - the pressure sensor has a light right on the toothbrush. I love it. I love the charger with the glass. It gives me such a feeling of joy to go and plunk the toothbrush right in the glass on my counter and it goes “beep beep” which my toddler loves of course. It goes beep beep, he goes beep beep, I go beep beep. It’s nice for him to see me empowered and content while brushing my teeth, it’s really important to me. I cant wait to go to the dentist next time, that feeling of dread, “uh oh I’m behind on flossing what am I going to hear” is just gone. My teeth are so clean, my gums feel so good, and I only brush twice a day and floss most days. I received this toothbrush to review as part of the Stellar Product Testing Panel. Thank you! I only wish I’d started using it years sooner, it’s made such an effortless positive impact on my life.

Is this too Gimmicky
I received the Soniccare DimondClean Smart 9350 rechargable toothbrush through the Steller Product Testing Panel to test and review. It looked a lot like the current Soniccare toothbrush is previously been using. It is not the same thing. This new one has Bluetooth and an app and new brush heads and a fancy, feels all fancy glass that you can use with the charger and one of the best features for me, a travel case with the option to charge! I liked the 2 toothbursh heads I tried out. One was the premium all-in-one and the 2 in 1. I tried both and I like both. The all in one is the one I'm using now because it's all in one but I think the 2 in1 is a good and probably cheaper buy if you want to upgrade from the standard brushhead. The sharging glass is a nice touch, but I don't use a glass when brushing my teeth so it's a bit wasted on me. It sits on the counter and I keep thinking I should have some spirits in it or something, nevertheless, the brush charges well in it when it is on the charger. It also has a really nice heft to it. This brush is Bluetooth enabled and you can use the Soniccare app with it. A long long time ago, I was using another brands' app and it was similar BUT I think I liked this one better. I have never wanted to please an app so much when using it to brush my teeth. It divides your mouth into 6 zones and tells you where to brush and the teeth on the screen get whiter as you brush them and then it moves to another location for another 20 seconds vs splitting the mouth into 4 sections for 30 seconds each. I have noticed that the 'teeth' on the app don't always get whiter as I'm brushing my teeth, so I get frustrated bc 'I'm brushing there!!!!'. But I do appreciate the extra time it will give you to 'touch up' parts where the app didn't registering you brushing that area as well. I did experiment with the various modes, clean, whiten, gums and clean+ so your can focus on certain areas more. It's nice to have the option and some minor differences for using the tooth brush. I really enjoy using this toothbrush and think that I am brushing it better but sometimes brush without using the app because I just want to mindlessly brush my teeth. I was also super excited to take this tooth brush in the case that can also be plugged into charge but forgot it!!! That was a huge disappointment for me because I had to manually brush my teeth for 5 days! First world problems I know. I think this is a solid option if you are looking to up your toothbrushing game and getting some feedback via the app about how you are brushing and making you more aware of what you are doing. Yes, it's probably a bit pricier for that feature but it's nice to check in once in a while and see how many brushes you have with the brush head, change where and how you want to focus your brushing and get more insight into your brushing habits.
