For 25 sqm it is small.. In the photo it looks much bigger... It broke and they replaced it for me. Helpful company...

I will agree with the comment that it is a miniature. It is a small heater. Definitely not for 25 square meters as it claims, at most 17-18. Depending on the dimensions and performance, do not expect miracles. For an 18 square meter room with moderate insulation on the windows, it heats well on the 3rd setting (11 fins). It has an automatic thermostat at around 10 minutes. It is quiet and does not smell. Very good for a bedroom and a child's room, and safer compared to gas or halogen heaters, etc. It works all winter day and night in the child's room and so far it hasn't had any issues. The increase in the electricity bill is within reasonable limits. The cable is satisfactory in length, lightweight, and easy to transport. If you want something economical for a small space, I recommend it.

Attention, the dimensions provided in the specifications are for the packaging box. In practice, it is miniature. The actual dimensions are 30W × 12D × 50H
