Query: Horrible Product

I bought this product at Petsmart and it is absolutely horrible. Poor design. Poor application. Will break or have to be reset every other day. If they used sturdier materials (and actual metal railings, gears and wheels) it might be effective but this product, as well as most other automatic cat litter boxes are a waste of money. Ten dollars worth of materials with a 100+ pricetag and it does not work like they say it does. Do not buy.
