Great product, fast shipping. I bought one, loved it so much I bought a second one. LoL
Seems to be built solid. I really can’t tell the difference between these and the AC Infinity ones.
Even the controller looks the same.
Easy too assemble, easy set up, quietest grow tent fans I have heard so far.
Very happy customer.
👍👍 Mars-Hydro

Great fan but the control won't change f to c and humidity control won't adjust... Been in contact with marshydro support and working with me to get a new one replaced when stock comes in hopen I get it... Really digging the mars hydro line up but sometimes things happen... It's all about what u do from there that really makes the difference and I believe this guy's got me so I will update u when I know what's going on
