I purchased this product over 5 years ago.  Love the fact that you can have one side "cooking" while filling the other.  Came back to read recent reviews as I was thinking of replacing my unit due to rusting issues.  Found that the parts I was having issues with had been upgraded on new models.  I contacted customer service hoping to purchases replacement parts.  Darwin from customer service went above and beyond.  The replacement parts arrived today at no cost to me.  Thank you!
