The fan is great! It's a lot quieter than I was expecting too. I installed this in my metal building man-cave and within 10 seconds I could feel the temp dropping. OK, amazing fan, but he best part was Vevor's stellar customer service! Like an idiot, I tried wiring it hot, as I do everything, and accidentally touched the black wire to one of the wires (I was wiring it direct), and it fried the capacitor in the motor. I reached out to Vevor and "fessed up", telling them it was my fault and I would pay for a new motor if they would/could sell me one. I got the nicest, kindest reply back asking for a few photos of it. I sent the photos of it and they replied that they were sending out a new motor. I swapped out the motor and rewired the recep, and wired a short extension cord (with the female end cut off). I plugged it in and it came on, the louvers lifted and the 24 x 30 building started to cool off almost immediately. My entire experience as a top-tier customer of Vevor has been extremely good, and I've turned a lot of my family and friends on to this great company. 谢谢
