Impressive device
Very satisfied with this great device. Love the different settings/brush functions after trying each and I can guarantee that my teeth have never been cleaner after using Philips Sonicare DiamondClean Smart Electric. I’ve used other brands (I will not mention to be fair since they’re cheaper) but Philips stands out all the better. If I may add, after using the deep clean mode, I felt like I just visited my dentist after 6 months f/u. I highly recommend this product; might be a little pricey but the reward is worth it. I got it as a gift, though.

Great toothbrush for managing oral health
This is my first Phillips toothbrush, and Iâm really enjoying it. While it is quite pricey, the payout is in minimizing issues at the dentistâs chair. I really appreciate that the app helps manage time spent in each area of the mouth, pressure, and scrubbing. It also enables you to flag problem areas requiring additional attention, reminding you to take extra care there. After reading some of the comments regarding concerns with charging via a cup, I was also concerned regarding how this may look. That said, I was surprised to see that there is an alternative option for a separate charging stand which is smaller in size and enables the toothbrush to stand upright. I prefer this option, and think it looks very clean and organized. I will second that the travel case does not charge the toothbrush itself. However, I consider this an extra luxury (an electric of toothbrush of this size is NOT one I would have ever considered âtravel sizeâ in the first place – a bit of clunkiness should be expected). I would be just as satisfied to pack the charger separately or temporarily opt for a non-electric toothbrush for lengthy travel. All in all, Iâm very satisfied with the quality of this toothbrush.

Worth it.
Letâs be honest, this is an expensive tooth brush (at least for me). But when you consider how expensive and painful dental work is, and how important dental health is, the cost is worth it in the long run. You know that feeling you have when you leave the dentist after a cleaning? That is what you get when you use this tooth brush. All of the settings are great, and effective. My teeth feel clean and smooth, gums healthy. Solid product.

Do Not Buy if you Have Weak Enamel
Iâm sure this is a great toothbrushâ¦but I made the mistake of purchasing this, knowing I have weak enamel. 2 months later, my teeth are destroyed. My once beautiful, white smile, is now discolored & the enamel is gone. I wish I never bought this. Iâm going to have to spend thousands in veneers to get my teeth fixed.

Best Toothbrush
I have been a sonicare user for almost 10 years. The quality of the product is amazing and if there is ever an issue with the product, their customer service is outstanding. So I am not a twice a day, or even regularly floss and my dentist is always amazed at how little to no build up I have on my teeth and never have any dental issues. The different cleaning modes is a great option and having the ability to change the vibration intensity. Yes, the price may seem a bit high, but to have healthy teeth and gums and never need expensive dental work, I would say it is worth the cost.

Perfect in all ways except 1
Our old one had the same case except the case had a charging port so you could travel with it in the case and charge on the go as traveling. This case isnât chargeable, only the cup is chargeable. 🙁 Love the toothbrush in every other way tho! Weâve used the same one for years and only had to replace cause we left it in hotel.

Philips Sonicare DiamondClean Smart 9300 Electric Toothbrush
I prefer these over any other electric toothbrush I have had. Before buying this unit I bought the higher end Oral B. Now I am back with Sonicare. Noise level is as expected for an electric toothbrush. Durable (although if you use to much force to brush with i notice it takes away from longevity of life), good design. Cost is always the big downfall for electric toothbrushes but I’ve gone the higher end models and don’t push too hard and I find value in the money that way.

I switched to this toothbrush from the well know competitor. The Philips is superior in the overall ease of use. I also feel my teeth are cleaner. Love the cup charger that is an actual glass cup over top of the charger! Being able to quickly dump the toothbrush into the cup to charge without having to align is very convenient. Any drips or residue falls into the cup and it’s a breeze to rinse/clean. The heads are a nice size and softness. I’m very happy. I bought another one for a family member!

This is the second one I purchased, as I was happy with my own and bought one for my husband. It has a great charge, that lasts a long time when traveling. I like that you can remove the brush part, for packing. I also love that it comes with its own glass, for charging, and when rinsing your mouth. Mine has lasted quite a long time. It is the brand that my dentist recommends.

I like the look (mid-gray) and feel (high quality plastic). It’s more “energetic” than previous Sonicares I have owned.
