    Would never switch back to manual brush. Love the Phillips Sonicare. Always updated and improved with each new purchase.

    Strong and durable. The multi-modes are great as well as the built in timer for settings. The multiple heads for different coverages are great as well. Nothing bad to say about this product, wish i purchased sooner

    Purchased this brush to replace an older Oral B model. I like the sonic action better than rotating brush head . The brush is loaded with features and love the gum health function. The charging stand and glass are unique. I use the app once in awhile. I have had the brush for 3 weeks and have already noticed a difference. Strongly recommend.

    Bought this as a gift for my GF and she loves it. Design and build quality is great and the motor is pretty powerful and leave teeth squeaky clean. Battery life is great and wireless charging works like a charm. No issues yet.

    I had never been into electric toothbrushes until a few years ago, and this 1 is the reason why.
