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.

Not about the product but the poor customer service. I tried to return due to being too large for my windows and company insist i have to pay when i contacted them with 16 days for return. The ticket i submitted was acknowledged but NOONE finalized my request and when i finally got online to chat the agent was insisting on not helping and wanting me to pay for return of my product. I have never had a horrible return experience like this one but i have to warn customers, if you buy its yours! Buyer Beware.

Fan came with one louvre bent. The aluminum is very thin and was able to bend it back. With light wind the louvres flap open and close making it noisier than the Canarm fan opposite side of greenhouse. Same size fan but much much lower cfm than the Canarm which was twice the price. Really proves you get what you pay for! Very short electrical cable to make your connection.

While the service was prompt, when I put the fan in, took the tape off and started it for only a minute, the shutters became bent. I have asked for a refund or a fix. I will see how they respond

Se produit est très médiocre il est fait fragile le mécanisme des palette qui ouvre est aussi fragile qu’une feuille de papier et même avec une huche de protection extérieur un faible vent fait fermer les palette et le moteur est toujours très chaud

This Vevor fan have a very bizarre design, personally I will call it a bad bug. If it see 0 degrees Celsius, it start the fan. Another bug this fan have is look like the 0 Celsius is not really 0 Celsius well adjusted.... Why 1 stars on 5. That happened to me today the second day I use it, This Vevor fan killed most my plants this year in 2026 in my greenhouse .... I noticed this morning the Vevor sceen shown 100 (100c ? while temperature was in reality 1-2c around temperature sensor) with the Vevor fan at full speed bringing the night -10c inside my greenhouse and my heating system got defeated... (Killed most my plants by the way.) It was the second day I was trying this Vevor fan. Very frustrated and this will cost me money and time.... 1 star on 5... How to disable fan starting function at 0c ??? And why showing 100 ??? I have no idea...
