Question: Are the controllers noisy?
Document: One of the two controllers started flashing uncontrollably after 3 days of use. The entire display just kept flashing faster and faster until the backlighting was the only thing flashing. I've contacted the manufacturer and have to ship it to them, at my own cost, and wait to have a new/replacement one shipped back to me.
Love it! We live in the very cold state of Minnesota and I work outside for several hours a day and get chilled to the bone. It's so nice to crawl into bed and have it already warm for me. Nice to have dual controllers so my husband can set his own temp. Would recommend this product to anyone else that has to work outside too.
I did much research on many of the different heated mattress pads and am very pleased with this model. A few "bonus" options on this model that are not noted in the product details:1. Time SetYou can set the time on the controllers (see why you'd want to do this in #2)2. Set time for Pre-HeatBy setting the time (see #1) you can also set a time for the mattress pad to start the pre-heat function.
The mattress pad component of this product is excellent. High quality materials and luxurious feel. Very comfortable to lie upon. The reason for my low rating is because on the second night of use both controllers indicated a P2 code. I referenced the owner's manual and followed the trouble shooting instructions. After carefully taking the actions described I reached the point where the instructions indicated that the mattress and controllers needed to be returned to the manufacturer.
There are many things to like about this mattress pad; it's soft, I can't feel the wires, and it heats up quickly. But I wanted a mattress pad that I could set to turn on at a certain time, and shut off at a certain time - this one can't do that, despite what it said in the description. I wonder whether I received the correct controllers?If I can get this issue resolved, I would give this pad 5 stars, because it's really nice.
really feels great in camper! Climbing in a warm bed sure is easier than climbing in a cold one! Look forward to it!
made of soft fabric, easy to adjust 10 setting dial. Makes for a cozy bed on those cold winters nights. Two separate controls for each side of the mattress.
keeps me warm as toast - duel control allows absolute control- simple to use - worth every penny I paid for it,
i received a used item. it was not packed in a plastic bag there were no documentation or any paperwork and no electronic controls.
You're told not to hide the cord between mattress and box spring, so that means the cord runs on the floor. If you have a bedskirt, that also means that the cord runs down the box spring in front of the bedskirt on the most &#34;public&#34; face of the bed, and then across the floor to the nightstand -- not what I'd call high style. So, 4+ stars for function, 3 stars for style.
Answer: Not a peep.
