We shopped locally for the Chef's Choice 645 Slicer, but couldn't find one in-stock to inspect. After reading the factory description of the unit, we resorted to online ordering. When it arrived, we carefully unpacked it so we could examine it closely. What a BIG disappointment! The 645 had too much plastic in the construction which we had not been able to see in the photos we could find nor was it mentioned in written descriptions. It is a plastic device with a metal shell that is primarily for appearance. We repacked it and returned it to the vendor. This experience isn't free since we will be charged a restocking fee and shipping. Learn from our experience. See it before you buy!
