This specific blanket has 4 intensity settings. After 10 days of testing, I ended up using it on the 2nd level. For better functionality, I combined it with a timer so that it opens at specific hours during the night, as the built-in timer only has one function (2 continuous hours) and then it turns off on its own. The blanket goes under the sheet, warms up very quickly, and overall I am very satisfied with both its performance and consumption (53 watts with a meter in the socket).

First of all, as far as the quality of the mattress is concerned, it is very good.
The temperature settings are 4, so you have better control.
The fleece is soft and you also don't feel any resistance.
Overall, in terms of construction and warmth, it is very good.

Now here comes my question though...
What's up with this timer???
It says "Automatic shutdown in 120min."
I thought that if you get up and forget to turn it off, it would automatically shut off after 120min.
But it starts counting as soon as you activate the mattress.
So, let's say you go to sleep at 11pm and after 120min, when it automatically shuts off and cools down, you have to set the dial to "0" for 5sec and turn it on again to deactivate the timer...
I can't understand the logic behind it.
And that's why I returned the mattress in order to get a different one.
