    My dental hygienist recommended Oral B and I’m glad I switched. I used Quip for years and this is definitely more powerful and I can tell it’s making a difference.

    Wow! Super clean feeling when you use this. I already opened a nice oral B toothbrush but saw this and saw such good reviews I decided to try. I cannot believe the difference! It does such a great job!

    Love this electric toothbrush. I have tried others but I truly like the features this one has. Especially how it notifies me if I’m placing too much pressure when brushing.

    Although expensive for a toothbrush, it's been well worth it for me. My oral hygiene is so much better and my dental hygienist always compliments my teeth for being so clean and healthy.

    What a toothbrush. You feel the clean. Charging is simple and love the pressure gauge while brushing. The software for iPhone is a little buggy but overall the beat toothbrush out there.

    Definitely would recommend. The digital display is great, but if you use the Oral B app with this brush it greatly increases the value. Not only does it track where you’re brushing, but also how hard or soft you’re brushing. The brush also came with a few replacement heads as well. Overall its a great motivator to have better dental health with the help of awards and coaching.
