    I've had this for about a month now & so far am really enjoying it. It's definitely helped me to be more consistent with brushing my teeth. The toothbrush cleans well & is easy to use. Connection with my phone/app is sometimes not the best but turning bluetooth off & on again seems to fix every time.

    Good power and adjustable! You can literally feel a difference after one brush, it’s nice to have that feeling like you just came back from the dentist. The battery life is good and the convenient travel pack is the best!

    I was shocked when they said the price at the register..... I clearly thought the sticker said something else. But I thought, my teeth deserve this, I was wrong, no one does. It feels like your teeth are being cleaned by angels with silk brushes.... in bikinis. It’s worth every penny.

    Unbelievable Clean Teeth

    From the first time that I used the Philips Sonicare tooth brush system I could notice the signifigant improvement in the cleanness of my teeth, closest to my gums. My teeth feels porcelain smooth right down to my gemlike. When you are brushing you can feel the toothpaste and water flowing between your teeth, the sonic vibration moves the toothpaste through nearly flossing as you brush.

    Although it might seem pricey, it’s worth it. This toothbrush does a great job. The real test will be when I see the dentist. It comes with different brush heads. There are specific brush heads for this model for certain features to work, like the app. There is a travel case included. The app helps keep track of missed areas. My teeth did get a little whiter and are clean. It’s a great quality too. I’d rather have a charge stand than cup that sits on a charger but the cup can go into the dishwasher.

    Best Sonicare Toothbrush

    Best electric toothbrush I've ever owned. I had gum disease and my dentist noticed the difference asking me if I have been using an electric toothbrush and flossing everyday. Don't hesitate to buy this Sonicare. Amazing!

    Powerful Cleaning

    Upgraded from a previous sonicare model (healthy white). The iPhone app is a little buggy, recognizes this brush as a lower end model and occasionally tells me I’m using the wrong charger (the same charger it came with). However, the powerful cleaning on this brush is top notch. Teeth and gums feel clean and healthy.

    Expensive but so far so good. I've only had the toothbrush for a couple of days but my teeth feel really clean. I had an old oral b and this one definitely takes getting used to as it is somewhat loud and odd to hold until you get used to it. I got this one as it gives you a lot of replacement heads.

    The best toothbrush out there. I feel like I just had a professional dental cleaning every time I use it. Beautiful blue color with plenty of settings and the glass cup charger is very cool and convenient. It also comes with a rechargeable case for travel.

    Purchased this Sonicare toothbrush as a replacement for my previous Sonicare. This toothbrush has an app that connects the Sonicare to my iPhone. Using this app, I discovered I was not brushing correctly in two areas and I have since been able to correct this. I'm very happy with my purchase.

    The app that works with this toothbrush has shown me a lot I didn't realize like the pressure I was using as I brushed to where I took more time and where I needed to focus more attention. I am so happy I upgraded my old toothbrush.

    Love my toothbrush. Yes it’s expensive, but my dentist told me I was not spending enough time brushing some spots. Went back to the dentist and he said I was doing much better. I told him about the toothbrush. He said he would suggest it to his patients but legally can’t, but would if he could.

    Easily the best purchase I’ve made in a long time. It’s expensive, but worth it. ZERO plaque build up since I’ve started using it. Sonicare did a great job making this. The charging cup is a little weird, but you’re used to it in a day and done even notice it. With the Best Buy warranty, it’s really you can’t beat it. I waited til it was on a deal of the day, but if you wanna take care of your teeth sooner just do it. I bought one for each of my family members.

    Great product but overpriced! I received an amazing deal on this product and coupled with the included heads, I decided it was worth keeping. Its a little gimmicky and I do not use the app as one must register and usage in monitored which is too intrusive. This is my second Diamond Clean and I am sold as I have had zero issues with my dental care since utilizing this product. Based on the price point, I cannot recommend (Unless you get a great deal) as the lessor models do the same.

    No, I would not recommend this to a friend
