I was in a house with windows made of pvc. We had 7 degrees inside the house during the winter. The truth is that this heater saved me, it produced a lot of heat and quickly, but as you can understand, if the house cannot retain the warmth, no device is to blame. I give it one less star because it consumes A LOT OF ELECTRICITY. I mean, I do not recommend it as a solution because even though it is cheap, you will pay for it later with a high electricity bill. But, to be honest, most heaters are like that. Maybe you should look for another solution...

I have had it for about 2 years to heat the bathroom in the winter. For its price, I consider it satisfactory, it heats it up quite quickly, I just wish the cable was longer

This particular heater was purchased last year. I use it in the bathroom. It had a problem with the thermostat. Specifically, when it operates on the second setting at 2000w, it automatically drops to the first setting at 1000w, resulting in inadequate heating of the space, approximately 5 square meters. Due to this issue, I do not recommend it.

I have had it for 2 years now to heat my 20sqm bedroom and only on the high setting can I say that it does some work. It is also quite noisy.

It does a decent to good job, mainly got it for the bathroom but also for the other rooms when I want to heat them quickly. Good construction and probably withstands the test of time. However, people who have experienced metal and some plastic heaters from 7-10 years ago will be slightly disappointed. But even the resistance is now measured with a dropper. In the last 5 years, I have bought 4-5 different types and this is one of the best

I bought it exclusively for the bathroom that the air conditioner doesn't heat up. For this job, it's fine. The cable is borderline for a high bathroom outlet.
