Works wonderfully by simply twisting bottom part of the handle- backwards! Ta da! I also prefer the angled curved shape at the top (for face) compared to more expensive brands on the market. Easy to clean too. Had mine about a year now with no problems and battery still going strong. Quo often has 50% off sales. Can't even go wrong at full price for this handy dandy, well made device! Competition charges way more…and for what? Btw, very happy with any of the Quo skin tools so far. And yes, switched from buying the overpriced brands that aren't necessarily better quality. The Quo tools are solidly built. Rare thing to find in beauty tools.

Put in a battery and realized there wasn't even a way to turn on the vibration. Packaging is deceitful.

Stopped working within a week of purchasing it. Tried replacing the battery but still won't work anymore
