Works well, does what it's supposed to.
I bought my unit for ventilating a basement. After about 2 months of continuous use, it stopped working for seemingly no reason. It was past amazon's return period, so I contacted Turbro's support. They sent me a new unit the very next day! I'm back up and running no problem. this thing can move a TON of air. And while it's not super quiet at the max speed, it's very reasonable. I keep it at a relatively slow speed, so it's pretty dang quiet for me. As long as this replacement unit holds up, I'll keep this as a 5 star review. If the new one dies like the old one did, I will likely update it.

Quality fan
Fantastic fan. Moves a lot of air. The speed adjustment works smoothly. I've had one running continuously for over two years and it's still going strong. Nice and quiet too.

Very nice, quality, made to last
Really powerful little fan. It’s made of sturdy metal and feels like it’s made to last. The settings run 1-100 and it’s very sensitive/responsive when turning up or down. When on full blast it can get loud but that’s because it outputs air like a jet engine. You can probably find cheaper fans that are similar size but this one is probably the best quality you’re going to find.
