Customer Reviews for VEVOR Shutter Exhaust Fan 624 mm Wall Mounted Automatic Louvers Silver, Sturdy Steel Housing, 6679 CFM Low Noise, AC Motor, Ventilation and Cooling for Attic, Garage, Barn, Greenhouse, Workshop

Have the fan and controller installed, the fan goes off and on all the time! Not happy with it!

The fan would not work. The blades touched the frame. Had to bend each blade to make it work. May be a little imbalanced.

There's absolutely no way this fan moves almost 7000 ft.³ of air per minute. It's rated at 6900 and it doesn't even come close. I have a $50 floor fan that moves more air and that's not an exaggeration. The fan barely blows hard enough to keep the louvers open. I bought the 30 inch version and I'm very unhappy. I've already installed the fan so I'm not taking it down but I should've just spent the money and bought a real industrial attic fan.

Install was great, quality looks great, only problem is it has a loud resonant frequency. High speed or low speed, it is always there, same frequency and same loudness

Very noisy fan at low speed

I had a few issues with this product like the cord not being long enough the fan speed control looks like it has a lot of options but when you set it on anything close to 3/4 or more of its highest setting soon as you let go of the knob it moves itself back down to under 3/4 speed so unless it's only mine that does this there's no need for a knob with that many settings if 1/4 or more don't actually do anything

The fan sitting on the table does not even provide enough CFM to even open the shutters a 1/4 of the way. I have 8" fans that produces more CFM.

The fan stopped working the 2nd week of using it

Tried customer service and they are terrible, thermostat doesn’t work!!!!!

I order the product last week and as was sawing to get it after 2 days I just received today after 5 days and the package is damaged. This is not professional I don't care who's fault is delivery company or vevor but this is not acceptable.
