The heater is very efficient for small spaces mainly, like the bathroom. Personally, I use it in a room of about 18 square meters and I can say that it heats it very well and quickly in TURBO mode, while afterwards switching it to ECO maintains the space warm with a sense of comfort and reduced energy consumption. Also, the noise levels are tolerable even in TURBO, in the case of ECO I can say that it is almost silent. Another positive is the protective cover that prevents moisture from entering the operation switches when used in the bathroom. The cooling function via fan has not been tested yet. Finally, the big negative for me is the strong smell of burnt plastic in heating mode, regardless of TURBO - ECO and thermostat setting. Initially, I thought it needed to run for a few hours and then it wouldn't smell. However, even after 5-6 uses for a considerable time, the smell remains although it is not as strong as the first time. For this reason, I deduct one star as it causes discomfort in breathing and may be harmful to health. If the smell stops after more hours of use, I will return with an update. Overall, it is a product worth considering and purchasing as long as it fits one's needs with the price being reasonable based on what it offers.
