Great material / thin enough so as not to scare you

The material is light "silky" or "velvety" but of course slippery.
It does not feel so cold, like standard silicone.
Also the supplied bags of black velvet was well received. Is just for girls ;-)

The different rhythms are described as funny and surprisingly very noticeable.

The only complaint is the inadvertent switching to the next mode or the unwanted off during the game. The knob on the rear caps's much too easy to trigger.

If the button installed easily sunk, one would not constantly around or off.
