    Philips Sonicare - Diamond. Guarantee!

    I used to have a pervious model of this Sonicare Diamond toothbrush, but it got stolen. :( I was left with the carrying case and the charging glass. I bought the new model and I could not be happier. My dentist told me how great my teeth look and in how good condition my gums are!! when I was using an ordinary bamboo brush, my dentist was complaining that everything was wrong in my mouth and that I was not brushing enough and properly. Now, I have changed nothing to the way I brush or the frequency and everything is perfect. She says there is not much to clean! And I really feel the difference everytime I brush my teeth. Get it, I highly recommend it. I saw the negative reviews that it breaks down after half a year or a year, and from my personal opinion with the previous mode, that did not happen! It was working great for 3 years before it was stolen. However, I got scared and I also purchased the best buy plan for replacement for another 2 years. If it breaks down 3-4 years after I bought it, I will not complain, it will have paid off.

    It’s a great toothbrush; just use it once you feel your teeth are clean. I would highly recommend this toothbrush to anybody in the market for a better smile. This toothbrush is worth the investment up front and not having to give the dentist extra $$$ for extra dental repair services. The whole package comes with seven smart brush heads and one tongue head, and the fact that they’re smart, they countdown to how much more sessions you have with the toothbrush before you have to replace it, so already in the box, you get nearly half a year almost a year worth of brushes, so that’s a big plus. Last dental appointment received an excellent checkup from the dentist. No extra dental repair charges or additional appointments.

    We have had Philips electric toothbrushes over the years. It is easy to grip and nice to have different brush heads which we alternate so we are getting all areas cleaned. Recharging is easy by just placing in the glass charging unit. It save having to hook up wires. The only complaint is that over time the metal price that holds the brush unit get loose and therefore does not clean well. That is the reason we had to replace the previous toothbrush

    Amazing Toothbrush

    I figured this was going to be a great toothbrush, however, after my first time using it I realized it is an AMAZING toothbrush. My teeth have never felt cleaner and whiter. It does sometime mess up w/connnecting to my smart phone (so I have to reconnect it time to time w/the bluetooth feature) but otherwise I love the toothbrush.

    Great toothbrush, but very expensive. The app works well and the Bluetooth connection is very stable. There are only two real issues with it. 1) cost, it is exceptionally expensive, but the number of beush heads included helps to justify the price (over the 9300 series) a little. 2) the charging case does not have a battery, meaning to charge the brush you have to have the case plugged into the wall. For this price it should have a battery in it so it doesn't have to be plugged in all the time.

    Great vibrational toothbrush

    This is the second sonicare, previous was a first generation that still works. This one works just as well in a lower profile and more sleek package, the charging cup is cool too. Have never used the app, don't care for data harvesting so limit app use. *Almost returned it after using for two weeks...bumped the sink with the brush head while rinsing and it started vibrating very weakly, as in barely at all. The handle however would buzz really loud and you could feel the energy but it wasn't getting to the brush head. Super annoying and makes the brush a manual tool. Because this happend right after lock down this year decided to try and fix it myself. Was lucky and figured it out. Readjusted the elctro-magnet gap and used loctite blue for the set screws. Now the head vibrates like a nest of angry hornets! Handle is butter smooth and teeth are sparkling every day. Gave lower value and quality ratings due to high cost and poor quality assembly.

    I’ve been using the diamondclean for a month and love it. The app is helpful for brushing correctly and setting personal focus areas. The travel case makes bringing the toothbrush and 2 brush heads along on travel easy as the case includes an internal recharger if you forget to recharge it before your travel.

    Can’t start or end my day without it. Manual brushing doesn’t compare and after a week of using this you won’t want to go back. When used properly truly makes a noticeable difference

    May be expensive but it’s awesome! Plus you’re getting a bunch of brushes with it so it evens out the price some what! The app ability may seem ridiculous but I NEVER brushed my teeth long enough till I got on the app. Now I actually sit there and do it

    Over a year and still works like new and don’t have to worry about tearing up your gums or spotty teeth because this bad boy works great and i like it where you can use app and watch your progress on it while brushing your teeth.

    I love this toothbrush and my teeth feel as clean as when I leave the dentist! The sleek design and multiple toothbrush options were a plus for me! The only reason I am giving 4 stars rather than 5 is because sometimes the app doesn't report my brush time accurately so it affects my overall data for the week. The app can be a little slow to detect my brush as well. But the toothbrush itself is amazing!! So worth the purchase in my opinion!

    Absolutely phenominal! My teath never felt so clean except coming out of the dentist post full cleaning, now i get that feeling twice a day at home! One tip though, wait until it is in your mouth first before turning on or toothpaste will be everywhere. App is also highly impressive!

    Absolutely best toothbrush ever. Teeth and gums feel incredibly clean after use. I had Sonicare 9 years ago and an Oral B the past 6 years. This is a much improved unit compared to those devices. Highly recommend this toothbrush.
