The motor has more power than I will ever need. I stay around the middle range and it still keeps a steady rhythm when I apply pressure.
The clear window is more fun than I expected.
Hands-free use is the main reason I like it.
The mounted feeling was strange for about thirty seconds. Once I stopped holding the machine out of habit, the hands-free setup became the most relaxing part.
The thrusting is much stronger than the size suggests.
