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.

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.

Very cost-effective toothbrush
This is my second purchase. This toothbrush has a full range of functions, but I usually use the normal setting. It is friendly to my sensitive teeth and brushes them very cleanly.

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.

Big Sonicare Fan
This is purchase replace a previous Sonicare that finally died after several years. Everything you like about Sonicare is present in this toothbrush.Everything you’d expect this toothbrush to do it does. The build quality feels great and it supports multiple functions based on the auto-sensing of the brush head type. We brushing with the app is a bit gimmicky but I think it would be good for those who aren’t as conscientious about dental care.The one thing that did bother me is that this does not have the little hole in the bottom for inductive charging like all the rest of the line does. This has rendered my UV sanitizer worthless as it cannot charge this toothbrush. I’m not a big fan of the glass cup charging method. I found placing the toothbrush in the inductive charger is much easier. It also looks more organized rather than a toothbrush canted in a glass.

Really cleans your teeth
I resisted spending so much, but wish now that I had bought one of these years ago. It does the best job ever of scrubbing my teeth and disrupting the plaque just under my gums. My dentist complimented me on the new better care I have been taking with the aid of this brush. The battery stays charged for weeks, and I’ve learned that it’s best not to leave the stem in the charger once it’s fully charged. It comes with a travel case, and I won’t need to take the charger on vacation–because the battery lasts so long.

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.

This toothbrush exceeded my expectations. I finally decided to purchase after hearing great reviews from my boyfriend who also has this brand of toothbrush but in a different colour. The grey is stylish and I love that it comes with the glass cup and charging stand. Iâve really been enjoying this toothbrush and truly feel my teeth look whiter in just using it for a few weeks!
