I've had this icemaker over 3 years, after sitting unused it has rust on one of the cyclinders; it has mold, okay. But cleaning this machine therapeutically is very problematic. Since I purchased it it never gave me the size ice requested, choice there, but only makes large cubes. If unused it takes days to get going again. Buttons not user friendly in that it doesn't carry out functions as indicated. Would I buy again? No. I'd buy a cheaper one of foot the loss. I purchased because it had a good rating. I find it unsanitary in ability to self-clean and ability for user to clean it, and its construction.
