It has two settings, where one is not warm enough and the second one gets too hot.
Also, after a short period of use, it changed color. I don't know if this happens due to temperature change or if the product is defective

srsly best solution for my problem my feet was cold and now I have no issues!! and is cheap on electricity consumption!

ok in its operation but I had the bright idea to put it under the baby's changing table so it wouldn't get cold and it got very hot resulting in causing a lot of stress to my partner and it ended up in the trash (the mat). I take off one star because it ruined my day.

I was looking for an alternative for when I sit at my desk so I wouldn't have the electric heater on all the time, which burns 1-2kw, and this particular product has worked well for me. I use it with socks; with shoes as shown in the photo, I don't think it would work.

After some time of continuous use on the high setting, I feel that my soles get excessively warm and I need a short break. On the low setting, the heat it gives off is not enough for me.

4/5 because I would like the settings to be more useful (e.g. low for socks, high for shoes), and because the switch is not far enough from the device for me to have it on the desk, so I have to keep it on the floor.
Overall, I think it's worth the money.

Very good and on the first setting it gives good heat. I forgot it on for 16 hours and nothing happened

Nice and warm. Be careful not to forget it on, it doesn't have a timer. Also, it's better to place it on a rug so it doesn't come into contact with tiles.

It presses many 100w mats below, it's 50w and I use it on the 1st setting. It doesn't have an automatic switch, so be careful not to forget it on, especially on the 2nd setting. It also works for the office with shoes!

Very good quality. Quite thick and it hardly heats up at all from the bottom side which is also non-slip. It has two levels of power intensity. On the first, it consumes 25Watt which for me is very satisfactory, while on the second 50Watt.
