Title: Very bad design flaws -- this unit is trash
Review: This unit works well at first ... but has several terrible design flaws. The grinder housing is aluminum and is held in place by a single screw which is supposed to lock into a small indent in the aluminum housing.After a few uses, the indent gets slightly enlarged, the housing of the holding screw also works loose and the grinder housing gets a little play.That wouldn't matter so much if it weren't for the fact that the hexagonal housing on the grinder only connects with the hexagonal nut on the motor shaft with about 1mm overlap.Thus, that little bit of play in the grinder housing allows the grinder to break loose from the motor shaft with even the lightest of loads, rendering the entire unit completely non-functional.What a piece of trash!
