Query: Not a Reliable Product Watch Out!

I purchased this recently and was happy to get one. My wife and i used it to make 2 sandwiches which turned out great and we were very pleased. However, a couple of days later we wanted to use this product for a second time and it would not heat up. The green light comes on which indicates it is heated and ready for use but it is not heated. Im very dissapointed in the reliability of this product. When it worked it worked the one time it worked beautifully. All im saying is be aware of the reliability issue when ordering online since you may be packing it back up and sending it back.
