Review on 🌀 Enhance Ventilation Efficiency with VIVOHOME Exhaust Variable Controller by Jimmy Jefferson

Bought this fan on 04/29/2020. On 03/20/2021 he started making a terrible noise like he was flying in! After removing it from my system and inspecting it, I found that the inside of the blade where it slides to the motor was "jammed". As a result, the blade will not balance properly and will rub against the sides of the fuselage, creating noise. When I contacted them about buying another blade they said they don't have one and they are sorry. The?! I can't get a blade to replace this in less than a year?! Wow! Now I'm stuck with a bladeless engine! I do not recommend anyone to buy this item! Spend the extra $$$ and get something that will last more than 1 year! Unless you're just looking for an engine, stay away from this thing! You will regret throwing your money away on this thing!
