Query: Too many parts inside cup.Coffee gets stuck.

This silly grinder has too many parts inside the cup. The parts are supposed to help clean out the cup. Instead, they actually help to hold coffee grounds in the cup. The lid even holds grounds. There are way too many contours in the cup. It cannot possibly be cleaned out. At all.Also, you actually have to stand there and hold a button down to operate the grinder. You can't walk away and get your lunch ready. You can't do anything, if it would require you to walk away from the grinder. How is this a good idea? Why in the world can't they have a switch that you turn on and walk away? It could turn itself off automatically, (We know this because that's what it does now; It turns itself off automatically).Summary - Pros: Cheap. <$20 Cons: Does not empty completely. Lots of extra plastic parts. User has to stand by it and hold button down to operate.
