I purchased this unit 6 weeks ago. It lasted for 5 grinding sessions before it broke.Customer support at Hamilton offered me to "cut of the cord" and mail it in, with a money order for $7.95 to ship it back.I have to run to get that money order and the spend around $10 total shipping a device that cost $24 new back and forth.So much for customer service.I'll get the new unit and see how long that lasts, next time I will spent a little more money on a quality product. I guess you get what you pay for.
