Query: Very Messy

I feel this unit grinds the coffee just fine. There are a number of sizes; however, be ready for a mess. It is impossible to empty this unit without the grounds going everywhere. I put a towel down and it still manages to go everywhere - the floor, next to the towel and on the towel. There are too many areas on the grinder where coffee grounds accumulate - on the lid, where the grinding comes out, when emptying the collection container - it is a mess.
