The most reliable thing I could find for a simple but quality construction substrate from a reliable company with years of experience and a 5-year warranty!!

Quality for sure. The bed in setting 3 becomes an oven. Just have it under the sheet and have the duvet on top. 30 minutes before you lie down, you put it on 3 and then all night on 1. You sleep like a bird.

I have it for 2 months and so far it does its job very well. Some comments say that it doesn't heat up at all on the first level. I disagree. The first level serves me to keep it open all night. With the third level, you can't sleep because of the heat. The third level is used to quickly warm up the area. For sleep, you should lower it to the first (or second level in very cold temperatures).

It doesn't heat up much at all. With 15 degrees in the room and the blanket on the 3rd setting, you're warm without sweating. Because it was the first mattress topper I bought, I didn't know what to expect until I happened to see another mattress topper from a different company, more expensive at 40 euros, and the heat it emitted had NO COMPARISON. By the time you got out of the bathroom (max 15 minutes), all the covers had warmed up-almost burned, and obviously you couldn't sleep with it on the 3rd setting.

It has three temperature levels. The first level is non-existent, the second level is just enough to feel warm, while the third level is verrrry hot.

It is the second mattress topper I have purchased! It is good for its price, you just need to turn it on at least an hour before lying down to warm up evenly. It only has 3 settings.. And unfortunately, it does not have a timer.

I have had the mattress topper for about a week and it is really good. A negative point for me is that the straps that allow it to grip onto the mattress are a bit fake and one of them has already almost torn.

Pay attention to the dimensions of the mattress, as it may be a bit small, even for a single bed. If you want to warm up the entire mattress, prefer something larger. This mattress topper is very good for warming up the useful area of the mattress.

The 3 heat settings are fully satisfactory for me, for now even on setting 2 I get very warm sometimes. Like all the mattress toppers I have used, this one also takes about 30 minutes to warm up properly.

It looks decent but it doesn't heat up much (on level 2/3 and even on level 3). Now, in terms of construction quality, it seems to be quite good, time will tell better.
The very good thing is that its resistances cover all sizes.

Edit: 2 days after using it, it only warms up very little now and it doesn't consume the watts that it claims in its specifications. And this happens at all heating levels.

Edit 3: After about 2 months of daily use, it gave up.

The heated mattress pad is relatively good. My estimation is that it is a good purchase. It naturally has some negatives such as understanding the resistances a little bit, but this is compensated by the fact that it seems sturdy. Time will tell.

It takes a little while to warm up... or rather, it works so uniformly that it reaches temperature without you even realizing it... the sensation it provides is very good and you don't notice it under the sheet... the only negative is the bulky clip that connects the cable to the mattress pad, it needs to be placed in a position where it doesn't bother you... value for money

They are the best, I am very satisfied because I have had it for over seven years and now it broke after seven years and in order to warm up well, it needs to have blankets or a duvet on top to warm the mattress well and evenly

Certainly, for the money it offers, it is a fairly good choice. The only possibly negative thing is that it takes relatively long to heat up as I personally would like it to heat up a little more. Otherwise, excellent product at such a low price.

For the money someone gives, it's quite good, of course it lacks the automatic switch and the ability to deactivate after a certain period of time. The resistors are on a smaller surface than the surface of the substrate, meaning their ends do not heat up

Very good product, I bought one for my wife and then one for my child and mother-in-law. In total, 3 in all. They are all very satisfied

At this price, it's hard to believe you can find a mattress that you don't feel the resistance of. This is one of those.
