    So far ive useed to deep clean twice on medium intesity. I feel like i just went to the dentist. Kid you not. My teeth have never felt so clean from using a toothbrush. My teeth feel like I just went to the dentist to get a cleaning. Well worth whatever this costs. You will be spending less time at the dentist for sure

    This is the best toothbrush I’ve ever owned. Even better than every other sonicare I had previously for the last 15 years. Very much worth the money. The travel case and charger is awesome. You’ll feel like you just went to the dentist for a cleaning after every use. Recommend 1000%

    It’s good and expensive. The only complain is charging. Last brush I had more charging than this but it is more slimmer

    This is an excellent electric toothbrush, very thorough clean and easy to use. If you are upgrading from an earlier Sonicare model, you will notice that the familiar outer/upper, outer/lower, inner/upper, inner/lower pattern has been split into a more complex 3 zone cycle—this helps you brush more evenly. The brush also senses if you are pressing too hard, another improvement. I don’t use the app—it doesn’t work very well and gives erroneous recommendations.

    I didn't know I could buy this type of appliance from Best Buy. The toothbrush is top-notch. My teeth are cleaner than they've ever been without a dentist. My dentist suggested this brand and I am completely happy. It was expensive but I figured I would only buy it once a decade. Hopefully, it lasts that long. I expect it will.

    This thing tells you when you don’t brush enough. It’s great. If you want the best this is for you. Love how I can see the battery percentage on my phone. If you want to save get the lower model. It has the same performance as the model under it but this one has the tech stuff. Great purchase. Love how the travel case is a charger.

    Feels like a dentist office visit each time I brush. Each mode offers a different brushing experience. The travel case is super convenient and allows charging while on the go. Love everything about this toothbrush.

    Love the design. It doesn't take up much room on the bathroom shelf and the buttons are flush with the handle so no more getting toothpaste into the crevices and making the buttons not work. Love this re-design of the handle. Holds the charge a long time so I usually don't even have to charge it when traveling,

    Love the toothbrush, made a noticeable difference on my teeth after about a month of use. The app is a little off with how long/where I am brushing but it still helps. The travel case is really handy and I love it.
