Query: Cheaply Engineered

I had an earlier model that worked fine, so I bought this one. BIG mistake. It is very noisy, the metal tined rake does not sift the litter well, and if the tines catch on something they pop the debris all over the floor when they snap free. Within a couple months the guide wheels broke off the rake making the whole thing useless. Customer service is abrasive and arrogant. Do yourself a favor and skip this one!
