It didn't work for me, sadly. I loved the quality--this is the first Fun Factory toy I've tried--but the cutout was too big for me, and I couldn't do the pinching without getting my fingers all the way around at the end, where it was just awkward to pinch and hold. I'm very sad; it looked so nifty. It may be one of those toys where the individual body configuration of the user will have a lot to do with its effectiveness.
