Due to the layout of my apartment, the air conditioner cannot reach my room, so I resorted to the solution of this particular fan. I have been using it for a year and I can say that I am thrilled. The microclimate it creates is exceptional, and now even during times of unbearable heatwaves, I can sleep comfortably even without covers. Ideal for rooms up to 15 sq.m.. The noise level can only be considered somewhat annoying on the high setting. Its socket can accommodate any E27 bulb (the most common on the market). Anyone purchasing this particular fan should not settle for the mounting screws provided by the product, but should obtain sturdier screws. The installation is of moderate difficulty, as it requires the use of a drill to make holes in the ceiling and basic knowledge of electrical wiring.
