I bought this mini heater / auxiliary heater in a store (I paid 10 more besides, I want to clarify) It is cheaper than others, spending 1,000 watts in eco, against 2000 therefore also economic energy and therefore money. It is noisy as all electric radiators but it's still manageable in eco mode. I should point out that, once started, it quickly becomes very hot and children desperate to get close (go figure lol) so watch your kids !! For cons, I find a bit short connecting thread anyway, bring an extension if you put me in as a "large" room. It quickly warms the room, even in economy and is super easy to use! I saw that he also worked in air conditioning mode, that is also why I took this model, in case I need it this summer. I will therefore recommend, no worries;)
