I agree with Adriana and Rocky. The push button is great for one-handed control, but it's far from convenient. I don't know what has changed since the last Evolved toy I received, but with my multi-speed Seduction, I had to actually cycle through the three speeds and off. So if I accidentally pushed the button during use, it would change speeds on me or turn itself off. Maybe if the button were on the side, or something like a grip-button, that requires pressure from both the finger and thumb to change setting/turn it off. I don't know. Just, the design as it stands could be improved.
