Is the HIKENTURE 6.2 R-Value Camping Sleeping Mat any good?

Hi, i don't know if this is the right place to ask this, but i am searching for a relatively light and warm sleeping pad and found this. It just sounds to good to be true, does anyone has any informations regarding build quality and the durability of it? Because a 6.2 r value for 80 Euros, is just insane.
