I received the mattress pad on time and securely packaged. The instructions are simple and straightforward. When first plugged in, the function dials did not respond, but remained fixed, flashing. I unplugged the unit, plugged it in again and retried the dials with success. There are two dials, one for each side of our king sized bed. Each side of the mattress pad functions independently of the other. There are 9 settings, ranging from L(low) 2,3,etc., to H(high). The unit has been in use for a few months. Typically, one of us will set the controls shortly before bedtime. Quite a luxury to climb into bed and settle onto nice, warm sheets. Highly recommended.

Who needs a heating pad when you can have this beauty! Also- the DUAL Controls are definitely worth the money @ $10.00 more! This way your significant other cannot complain of being too hot or cold. Definitely a proud purchase & would recommend this! I live in Texas & it's GREAT FOR MY SCIATICA!!
GET THIS- YOU'LL BE SO HAPPY YOU PURCHASED IT!!

This pad was easy to install, though I was a little annoyed that the instruction book gave different direction for different models but nowhere did they tell you what model you have. The skirt is voluminous, designed for very thick mattresses (you can't by any for thin ones anymore). I fastered all the corners down with straps as a precaution, but it may not have been a problem. At the highest setting this pad is too hot, but in the range of 4-6 it is perfect. The ten hour automatic shutoff works just fine. The pad appears fairly well made...it is made in China. This mattress pad perfectly met my needs so I would recommend it.
