I've had a couple, like the first vibe I ever had, the motor burned out after only a few uses. then I had another one that just fell apart. I went to change the batteries, and all the connectors for the electrical currents fell out. since then, I have been willing to shell out more money for a vibe that wont bite the dust on me so quickly.

I haven't used any toys that were terrible, just ones that weren't right for me.
