I waited to review this product to give my true honest opinion.  I am NOT a fan.  First off, the zipper broke about 2 weeks into use.  I cannot stand the noise/sound it makes when you turn over or try to adjust your body.  And now that it is warmer out, my bed is getting warmer too.  Please do not suggest it is my mattress (it is a cool gel) because my mattress was not generating any heat BEFORE I started using this pad.  I slept fine before using this pad and I will be sleeping just fine without it.
