    Works great, but I don't use the smart phone app. I would probably get the model without it if I were to buy again

    Better off manually brushing your teeth

    I purchased this item in August 2020, it came with three replacement tooth brush heads. By December 2020, it stopped working and I reached out to have it replaced by the manufacturer. It was an easy replacement and for the base for the tooth brush within days. As of August 2021, it’s stopped working and was now out of warranty. There is only a 6 month warranty on the toothbrush. I had no desire to drop another $200+ on a toothbrush that was only going to function for some months. I will say that when the toothbrush was working, my dentist did commend me for superior brushing that I’ve been doing. I’ll give credit to the toothbrush for that. However, the price of the toothbrush does not justify the length of its use and the additional replacement toothbrush heads associated with it. Take the extra 5-10 minutes to thoroughly brush your teeth. Your pockets will thank you.

    Every time I brush my teeth with this brush it feels like I’m at the dentist office. The vibration is intense at the highest setting. It’s an acquired feeling but leaves you no doubt that your teeth are clean. Well, that and the app that literally shows you the areas you missed.

    I love this toothbrush. I can now gloat whenever I go to the dentist since it tracks how you brush your teeth (how many times a day, how long, how hard, do you floss, etc). The app isn't as fancy as the one that comes with the oral-b brand, but it still does well.

    This is a very high end toothbrush. It does a wonderful job on keeping your dental care at top notch. It has several options in terms of duration and type of pressure to apply when brushing. There is even an app to help you keep track of your dental care.

    Let’s be honest, this is a lot of money to spend on a toothbrush, however that being said I am impressed. Works very well with each brush and I love the technology it comes with.
