So I've now purchased and set up 2 of these things and neither one turns on at all.

Which is making me think maybe I'm doing something wrong. Except that they seem so damn simple. But can 2 in a row really be that defective? Or is some bored petco clerk using them to play soccer in off hours?

Thoughts?

The things literally do not turn on at all when I attempt to use them. So far as I can tell it's full of water, and so the auto-shutdown shouldn't be going on.

Thanks!
