I believe it works satisfactorily in a space up to 12 square meters and is quite economical. Very nice appearance with electronic display and adjustment. I think it is worth its price.

We bought 2 pieces for the bedrooms of our holiday home, intending to use them at the beginning and end of summer (e.g. in May and October). For winter, I don't think they would be sufficient, but in October they were very good. My rating does not concern the winter period, but the season for which we have chosen them. However, I am not giving 5 stars because they consume quite a bit of electricity, the electricity bill came a bit higher.

We got it for our country house which is near the sea. In terms of appearance, it is perfect, very discreet and elegant. It makes no noise at all. We used it in October and it was very effective. We turned it on every afternoon and evening for 2-3 hours in total for about 2-3 weeks. Unfortunately, the electricity bill was significantly increased, but we didn't feel cold at all. For country houses and for limited use it is the best solution. However, for a permanent residence and for winter I wouldn't get it, I think I would look for a more economical solution.

This is an excellent product! It has nothing to do with previous models, it has an electronic brain with the thermostat working perfectly. The whole secret lies in measuring the room temperature of the heater. It depends on where you place it and where you have the reference temperature of your room (the thermometer, that is). The temperature inside a room is not stable, if you place it near an exterior door or window or on the northern external wall, the temperature can deviate up to 3 degrees from the indication of the room thermometer. (In my case, since I have it near the door, it has a 2-degree deviation). The heater has the ability to adjust so that the indications of the room thermometers and the heater match. Beyond that, the electricity savings are tremendous! In eco mode, which I have set at a constant 15 degrees, it only consumes 500 watts per hour, even though my heater is 2500 watts. Bravo to the French for their product! (We are always talking about the F120)

I have bought three, for the upper floor of the maisonette (Bedroom 12 sq.m., Office 10 sq.m. & Corridor 9 sq.m.). The insulation of the apartment is good, but the building is located on a hill (~260 meters, higher than sea level) and is mainly exposed to NE winds. I turn all three on every night (at 17.5 degrees) and in the morning I set them to economy mode (15.5 degrees). They create, within 10 minutes, a very pleasant and uniform atmosphere and the additional cost on the electricity bill is impressively low. I highly recommend them!!!

P.S. I see, in other comments, that some people complain about the consumption. Of course, if you set it to 30 degrees, it will obviously use a lot of electricity. However, given that, apart from its conventional function, it also has infrared radiation (!), I believe there is no need to ask it to raise the temperature too much. Besides, high temperatures are not good for your health! Of course, everyone according to their needs...
