Not really the best. Little beads on it are inconsistent and looks like they can fall off. They only saving grace is the vibe part, but even that doesn't go that high and is loud as a chainsaw. Just meh.
I bought this cause I thought the bumps on it would feel nice, but you can't really feel them at all. And also, some if them hadn't retained their shape- I don't know if they broke off or what...
The only saving grace of it is how high the vibration can go, though it does get EXTREMELY noisy after the 1st or 2nd setting. The dial is also pretty stiff; have to use 2 hands, and a firm grip.
Also, there doesn't seem to be a difference between this one and the blue one- becides a $20 difference.
