I really like this product. I have the namebrand version, and this is every bit as good. The first notable difference is that the bristles are stiffer than the namebrand version. That’s not necessarily good or bad, it depends on your preference. I am good either way, but if you don’t like stiff bristles On your toothbrush, you aren’t going to be very happy.The other thing that I really like is, it has multiple speeds for someone like me who has sensitive teeth, being able to adjust the speed is a nice option.The only thing that I don’t really like the on/off/adjust speed Button seems to be in a place where my hand naturally falls, so when I’m brushing, sometimes I inadvertently adjust the speed, or the unit unit offOverall, this is a great device at a, really good price
