Query: Disappointing

I bought two of these at a warehouse clearance (a catalog store for chefs). Therefore I can't return them. The first one didn't work out of the box. The second one quit working within the first 4 hours after being out of the box. Besides not working, they are noisy. Now I have two pieces of junk that I thought would be great, because of the brand name.
