Its getting cold during the past few days, and normally I would bust out my old electric pad, but during this year's CES (before the whole COVID) I saw a new type of heating mattress Pad at the show that use water to warm up the bed. I thought at the time it was an interesting idea, because from my experience using electric heating pad is like getting slowly baked in the oven, and I always need to get up in middle of the night and drink a cup of water. So when I saw this product on Amazon I figured to give it a try and it works great. Took me 2 minutes to set it up and the instruction guide was easy to understand. Sure it takes a little longer to heat up compare to electric pad, but you don't feel the constant heat, its a more warm and gentle, I would leave the temp at 90 degree for the night. Overall, I really enjoy the product and will buy another King size pad for my other bed.
