Bad review

This thing worked fine for 3 months when you plug in earphones. Then one stopped working.
Bad review

This is an excellent product for anyone with a cat or dog. No more cleaning up the litter all over. The only problem I had was finding good clumping sand to put in it. Just not as common anymore.

Good Review
