I recently bought one for $39 (U.S.) and then KAK sent me a note that they were on sale for $15.99 at a local pet club. If it has the name brand on it, I think you can trust it - they do go on sale quite often.

Mishi didn't like it, so now I've put it in Mitzi's spot. She isn't quite sure about it yet, but she had been drinking from it when I had it in Mishi's spot. We'll see. I does take time for them to get used to it.
