    I was looking for a replacement toothbrush. I needed to step up my mouth care. The fact that it hooks up to my phone is a plus.

    This toothbrush is a great quality toothbrush. Bought this brush for my wife. The only maintenance she has to do is change the toothbrush heads every few months.

    Since this is a (pending) Christmas gift for a family member, I cannot give it a fair review. It looks like a nice product.

    Smart toothbrush for better dental health

    The Philips Sonicare smart toothbrush is well-designed and loaded with features. Right out of the package, you notice the design of the charging stand--a metal base with an attractive, heavy glass. Just set the toothbrush in the glass to charge its Lithium ion batteries. The next thing you notice is three different-colored brush heads. Each one is designed for different purposes, e.g., gum health, deep cleaning or whitening. This Sonicare toothbrush is easy to use, with or without the smartphone app. Put a brush head onto the handle and select the desired cleaning mode. Add a dab of toothpaste and start brushing. The toothbrush gives you feedback if you apply too much pressure. To get the greatest benefit, use the free smartphone app. Download it from the Apple or Android stores. It is very easy to set up. Create a Philips account or login with Facebook or Google Plus. Once signed in, the app asks you to confirm you toothbrush model. It automatically senses which brush head you have installed, and asks you about your dental health goals. The app shows you where to start brushing, and for how lon. It tracks your progress. Pros: intuitive to use, with or without the smartphone app. Selection of brush heads. Discountbrush replacement program available. Great design. Cons: a bit messier than electric toothbrushes with rotating heads. Replace brushes for Sonicare are more costly than rotating brush heads for competotor's toothbrushes. Pricey.

    Amazing brush but the battery will not hold charge. So I have to exchange it to another one.

    This toothbrush does everything for you! It is so fancy and amazing. It has an app to connect to which tells you how long to brush each area. It buzzes and blinks when you brush to hard.

    Look this toothbrush! It is smaller and light than my prior model so fits in my hand much better. Does a great job cleaning teeth and gums.

    Technology is great, but the toothbrush did break after 1.5 months of using it, the shaft of the toothbrush broke. I did call customer service and they are sending me a brand new one and hopefully, this one will last a lot longer.
