Query: Small, cheap and works great

It's small and cheap but gets the job done well, evenly grinding things up. I mostly use it for flax seeds and spices. The cup is pretty small so if you need to grind large quantities of coffee I would not recommend this but for smaller grinding jobs I definitely would recommend this. This is the first coffee grinder I have owned so I am not comparing it to anything but I am really happy with it.
