This is the easiest toothbrush to use. My teeth after I brush they feel clean, it's like seeing my dentist ever day. I have gotten complaints on my smile. My teeth seem whiter and seem to sparkle. It takes a few trys to get the right pressure and angle but with the app it lets you know as you brush to hard and has a pattern to follow. So you will not miss a tooth. There is a setting that tells you when you need a new brush head or how many times more before your brush head what be effective anymore. You can decide what you want the toothbrush to do clean, white, gum heath or deep clean I'm happy with my Sonicare DiamondClean Smart Toothbrush.
