Query: Very disappointed overall

I purchased the Melitta grinder in late summer 2002. It worked for a few months before the motor burned up.During use, I discovered how messy the grinder is. You have to be festidious to keep the counter clean, and if a house guest trys to operate the grinder on his own, you end up with a mess.Once the motor burned up, I sent it unit back for replacement. They were helpful, and in a couple of weeks the new unit arrived, complete with broken buttons. The only way to make the unit behave was to unplug it.Now, immediately I have to send the replacement back for replacement. What a hassle. Cheap grinder = poor quality = frustration overall. Not smart to buy cheap products manufactured in China and expect them to last at least the duration of their value.The grinder has been more of a hassle than it is worth. A pain to use, works nice when it does, a pain to replace. I would have been better off investing a little more money and getting a better product.
