I recently purchased the Kitchen Aid rrk 1500b, The first time I used it the gears broke down after 3 minutes of grinding chicken. That tells me that they never did take this machine appart and recondition it, they turned it on and repackaged once they saw it worked.That is simply unacceptable procedure, and Kitchen Aid should be ashamed of themselves. I have waited 10 years to be able to buy this machine, and now I am really angry,and doubtful that I will recomend it to any one of my friend.CAVEAT EMPTOR---
