Query: Clean Your Kitchen After Every Use

While it grinds coffee decently, this is the messiest appliance in history, requiring me to pull out the vacuum every time I use it. Coffee particles literally spray across your counter as the grinder operates. After grinding, removal of the receptacle canister sets off a static explosion where grindings fly to every region of your kitchen. Seriously, it is almost like a bad joke every time I use this thing. Grinds go EVERYWHERE. I got this as a gift and it pains me to think that my friend spent so much on this thing. The company should be ashamed of the design flaws that cause it to operate the way it does. Oh yes, it will grind coffee... but the instant, substantial mess makes this thing unusable.
