It did not work properly from the first day, it would turn off after only five minutes without even raising the temperature by half a degree. After twenty days, it never turned on again.

-Good build quality
-Completely silent fan
-Takes a while to perform as it should.
-Placed in a 12 sq.m room.

1) The thermostat, even at the highest temperature, did not allow the device to work, so don't expect it to heat up quickly even though it has a fan, as it only operates for 1 second and then shuts off (in a 12 sq.m. room with double glazed windows, it took 4-5 hours to reach 18 degrees, while the electric heater I had only took 10 minutes).
2) The fan is inadequate and makes a lot of noise due to cheap construction.
3) Because the device opened and closed and sparked, the thermostat burned out and no longer works.

Tip - Take the oven out of the kitchen and place it with the door open in the air, upside down. It will be more reliable and make less noise. Hahaha... This device wouldn't even keep the room warm as well as a hairdryer

Value for money. I put it on full for about 20 minutes and then with the thermostat at 1/5 all night. It keeps the room at 20 degrees. (Put a digital thermometer to check the thermostat)
