One side heated up only once (1) and then stopped heating. I requested a replacement and it was done with a two-week delay. I haven't tried it yet. I will get back to you.

One side broke down in one winter. The heat at the highest setting was like the lowest of other underlays. The only positive was the timer.

The underlay warms up, however, the blanket has a fleece texture and gathers on the mattress, it does not stay completely stretched

Well, you will listen to me and no one else, stop buying cheap ones, buy this one for 40-50€. It has nothing to do with the others; when you spread it on the bed and put the sheet over it, it's almost like it doesn't exist. Also, the controls have many levels, and the switches are designed in such a way that they don't get stuck like they do in the cheaper ones. That's it from me, happy shopping!

Nice feeling, the ugly thing is that it has a cord of many meters and to secure it one must weave the mattress to secure it; two people need patience and thought! It's like weaving a spider's web. The only good thing is that it has a timer.... other than that, when I lie down I feel the tying cords both at the headrest and at the lower part of the legs.

The dimensions are wrong, 1.60 width and 1.50 length. The dimensions are giving me trouble. It's not worth the money. I have it and it takes up space in my closet.

I do not have previous experience with an electric mattress pad, but for this one, I can say that it warms satisfactorily and provides the warmth that was missing from my frozen sheets!!

It's perfect, it also has a timer. Wonderful sensation, you don't feel the resistance at all. Many temperature options (8).
P.S. I have had it for two years

I would really like to give the highest rating since the construction with materials and stitching is very good and beautiful... but it didn't work for us, mainly because the straps to secure it to the mattress are very weak, disproportionate to the volume of the topper (and not what the instructions show), resulting in the top edge flipping under the sheet and causing discomfort even though it doesn't move completely from its position. Maybe this is also due to its thickness with double material (it reminds me a bit of a blanket/throw). Additionally, the highest temperature on level 8 seemed quite weak compared to another product with only three adjustment levels! Of course, the timer is a big plus.

It is a great size at a reasonable price! It also has a timer, which is a very good option compared to the more economical ones that only have on/off
