The owner swore that it would work great.  I do not hear anything rattling.  There are no bad odors they would indicate an overheating incident.  I see normal wear only such as scuffs and scratchers.   Still, I will list the unit for parts or repairs.  I want you to feel confident about this purchase without an unnecessary return.  Shipping is $12.  8 combine shipping so please check out my other auctions.  Thank you for looking.  Ron
