Bests & Worsts Reviews from Amazon

I was prepared to really like this product. Had a couple of sweaters that I was really hoping would be looking, while not new, at least with no fuzzies. Got it in put in batteries, turned it on, awesome.... I worked on the bottom half of a sweater and all of a sudden the blades stopped moving and the system just stopped working. I switched out batteries thinking hey maybe I picked up some bad batteries. Nothing not even a half a turn of the blades. Returning to find a different product
