I purchased a Champion wq120d shredder from WalMart. It jammed and wrapped up 2 weeks later. I took it back and exchanged it for another of the same. It lasted 6 months and same problem. I followed the instructions and lubricated it as directed. The middle blades bent and Papper wrapped around the blade assembly. This was the most expensive one WalMart carried and I checked today, they no longer carry it. I called Axeus/ Champion and asked if replacement parts were available and they weren't. I will not be purchasing another Axeus/ Champion product.
