First, I'd like to compliment the design of this gorgeous toy. It is one of the softest and smoothest toys I've ever had the pleasure of touching. It's butterfly shape is just perfect. I LOVE that it has a warming feature. I've never had a toy include this before, and its so nice! It has 10 different vibrating variations, using 3 different speeds. Slow, medium, and fast. I just feel like once you put the toy inside, the part that sits on your clit isn't as powerful. It's charged via USB, which makes it wireless & portable. On it's highest setting you can definitely hear it buzzing, but I bet you could put it on the lowest speed and wear it in public. Overall, a great toy!
