I have this toy. The vibrations aren't the strongest, but it is very fun to play with. Basically, it has a touch pad that is pressure sensitive: you just push down on the pad, and the harder you push, the stronger the vibration. You can program vibration patterns into it and let it play over and over if you want, as well. It is 100% silicone, waterproof and rechargeable.
I gave this review to another member:
"I actually think it's a lot of fun, but it does have kind of a "prototype" feel to it: there is a rather noticeable seam on the sides and the touch pad looks to be connected and "glued on" by hand (and is thus ever so slightly uneven. The touch pad itself is filled with air and I'm not sure exactly how it's built, but it is quite responsive. Very little pressure is required to get light vibrations. The strongest vibrations aren't really too strong, maybe 2-3 bees depending on your point of view (I consider Mimi and Form 2 to be 5, and Elise to be a 4). You can either change the pattern in "real time" or you can program a pattern into it using the touch pad. It is very quiet and easy to hold. The silicone has no give at all (like the Lelo vibes), but is very soft. Charging is simple, like the Fun Factory vibes. It is also waterproof, but I haven't taken it into the bath.
I think it's cute and fun to play with, but it didn't knock me off my feet or anything."
