Great value and performance.
The set-up was easy, followed the instructions about the sequence of plugging things in and I had no problems.  We had a mattress protector already and the heated mattress  pad was placed under that.  I cut two slits in the protector skirt for the cords to come through.  The queen size has two controls and it requires an outlet for each one.  The heat can be felt within seconds of turning it on.  When I use it #1 temperature is enough, wife changes between 1 and 4.  The timer feature is handy but she just turns it off when she gets hot.  We have used it one month and wish we had gotten it sooner.
