The product fits really nicely but has dual controls each with it's own plug, which is a problem, depending on how many outlets one has behind their bed.  Additionally, the boxes that the controls plug into (and there are two) are on the top surface of the mattress pad so that you can feel them with either your hands or feet.  To tell you the truth, I would have returned this item, based on these issues, but it's just such a pain in the neck to do, I'm keeping the pad but wanted to share the feedback.
