So this is the model IZ-9031+ which has a DC motor, at 65 watts and has 6 rotation speeds, and not 3 like the previous model (Z-9031) which has been withdrawn from the importer’s page http://www.benrubi.gr/. I have had it since May so I can say a few things. From the 5 stars, I remove 1 because on the site and in the product manual, the technical specifications do not mention anywhere how many RPM (rotation per minute) the fan rotates at each speed and how much air it pushes CFM (cubic feet per minute) or (CMM cubic meter per minute), so I cannot know since I have no other to compare if it is powerful or not. I also remove 2 stars because when the light is off and the fan is running, the light flickers as if I have a Christmas tree on the ceiling; it doesn’t do it all the time, so it remembers, there is a chance it could do it all night or not do it at all for a week. Beyond that, everything else works normally, I don’t know under these conditions how long the LED light will last before it burns out. It’s really a shame because in terms of design it’s great and it’s dark brown which fits perfectly with my house, that’s why I bought it. I placed it in the living room and was thinking of getting 2 more for the bedrooms since at the first 2 speeds it is completely silent and at the third it is barely audible, but the issue with the light worries me so I will probably try something else. Finally, regarding the installation, if you have handy hands and the tools (hammer drill, etc.) you will install it relatively easily, if not you will need an electrician.
