After ten years it finally died May 9, 2003
Reviewer: A Customer from South East Florida

I bought a MJ-550 about ten years ago and will swear to the health benifits of wheatgrass. I think that you are a little harsh on this great home model. I have used mine every day for the last ten years and I think the bearing finally froze up. I don't know if I will spend money to upgrade after such great service from a machine. Although, I do know how to properly use a small grinder and not to overload it with too much product at one time.
