The overall design of this unit is very nice and "heavy". The one real problem? There is a main plastic gear, driven by what appears to be a casy aluminum one that has a tendancy to strip out. At first I suspected that the gear was made plastic for a reason - so it would strip out in the case of an overload (it does seem to have an overload protection feature also). So, I called up Fellowes and asked for a replacement part - yea... no can do. We don't sell that part. Sad, Sad, Sad. Back into the box it went.
