Query: What a great idea

I purchased this last christmas as a gift for friends that entertain alot thought it would be great on their kitchen island. I was so intrigued i treated myself to one also. used it recently worked great . You can either heat it up for the 8 minutes and unplug as advertised or leave it plugged in. Kept food hot . I am purchasing another one as a gift this year . GOt it At BBB with coupon.
