Apart from its mediocre build quality, it is a decent heater for its size! It heats up a room up to 25 square meters quite quickly. In a larger space, it takes more time as expected. If there is a thick carpet in the area it operates and moderate insulation, then the warmth lasts for a long time. It definitely cannot replace oil or gas heating, but as a solution for local direct heat, it works well. It doesn't have much impact on the electricity bill as long as it is used wisely and efficiently! It requires caution in usage because due to its mediocre construction, it can easily be damaged and possibly one of the 3 bars may break.

I bought this specific heater for the bathroom because I have a baby and I don't like air heaters. It warms the bathroom and one ladder very well. However, one ladder broke relatively quickly.
