This is a fabulous little friend. The settings are all particularly wonderful, and it moves FAST. There is pretty much a setting for every preference. That said, when on the highest setting, it can get pretty hot! I mean in terms of temperature, as the plastic heats up pretty quickly when it gets going. That isn’t necessarily a bad thing, but it might not be the type of thing some people are looking for. I also love the rechargeable quality and the easy to use base. Bye bye batteries!
