I bought it to dry some canvases at my workplace.
For what I wanted, it does the job. However, I wouldn't recommend it as a heater, as it is quite noisy and doesn't provide substantial results.

Useless from me as well.
I bought it for a workshop space and I knew it wouldn't fully cover the heating needs of the space, but I wanted to replace the portable heaters we had for local use.
Well-made, I must say, but useless, guys. It has heating elements, but it also has a powerful fan that, apart from the noise, disperses any heat from the elements, but if you stand 2 meters away, it only brings you cold air. Now I'm in trouble. If they don't replace it for me, I'll have to see if I can find smaller motors for the fan, at least not as powerful. I put them in a space (two pieces) of 25 sqm and they didn't lower the temperature even one degree after 2 hours. What a shame.
