Title: Spend you money elsewhere.
Review: I have had this for a few weeks now and I am greatly disappointed. This warmer only warms the middle of the mattress leaving the sides cold. Once it is turned off the cold returns within a few minutes, which is OK if you sleep with in turned on, however for the sane that would just like it to get the bed warm before going to bed this sucks. Thinking about putting it on a timer? That doesn't work because it does not remember your setting after the timer shuts off. If you want something that works better, get a dog and let him lay on your bed an hour before bedtime.
