Cleans my teeth really well. I like the 30 second vibrations (so you know you’re cleaning for the right amount of time) and the red light warning that you’re pressing too hard. You can see the red light easily and just ease off a bit. I never really use any of the speeds except the first one, you need to press the button multiple times to scan through them and I just don’t care enough to do that. I haven’t hooked up any Bluetooth.
