WISHEAD Heated Mattress Pad Queen Size, Electric Bed Warmer with Dual Controller, 9 Heat Settings & 10-Hour Auto Shut-Off, Machine Washable, White

This Heated Full Size Mattress Pad comes inside a big box that is inside a smaller box and then is shrink wrapped in plastic. It has 7-Heat Temperatures and a Timer to stay on 2-hours to 10-hours. There is a nice size digital display that lights up. This means no grabbing in the dark for a light when you want to check the controls of the Mattress Pad. It heated up nice and fast and the pad itself is covered with a soft cotton material. I have own heated pads before that were just vinyl and all night long you felt like you were lying on a plastic grocery bag.

I'm using this heated mattress pad on my California King mattress. It fits well and has deep elastic pockets, so it works well on thick and thin mattresses alike. This one has 2 controllers which is nice (and expected for the larger mattresses). I have always had heated mattress pads, but this is the first one with inline controllers. I guess they will be ok, but I think I prefer the controllers you operate on the floor. The cord that plugs into the pad is up the mattress a bit by your feet. In theory you shouldn't have as many issues with the cord coming unplugged. This is an AC mattress pad (130 Watt) . There is no DC convertor/transformer block. I would feel better about DC personally but that is just my preference so I will not rate low for it. There is debate if DC is healthier or safer but you can google that and make your own decision.
