First time use of this product. Was just what we needed. They stay on better than you would think. Would buy again. Easy fix. No bubbles.

The power plug fell out within 30 days of purchase with light use. It won't stay in. Had to buy replacement.

Ex Output:
Bad review

Ex Input:
It was okay, I just don't have a cat and had hoped it would be more practical than the Cat Dancer on my old cat. The way it attaches to her collar doesn't seem secure at all - she keeps getting tangled up in it. She did learn how quickly she can jump from this thing into the old cat dancer but it's not really good for her.

Ex Output:
Bad review
