Review: Works - Installing was easy, worked well this winter to keep our kitchen warm,noise wasn’t an issue
Review: POWERFUL, especially for the low wattage. Love it. Won't buy cosmetically-marked-up fans again. - I don't care about plastic housings and I'm happy to wire my own switches where relevant, so for me and the applications for which I use fans (in this case, cooling inside my truck/paired with optional swamp cooler water flow), this is awesome bang for my buck. It's a bit loud but I don't care, that's to be expected when going for something with high airflow. I do wish I'd considered getting a couple of different sizes because this is actually more powerful than I need for its current use, but that's fine, sooner or later I'll move it and the attached swamp cooler setup I built to a different larger space and build a new smaller one for my truck. I'd much rather overengineer something than have it be insufficient (like my first pitiful swamp cooler attempt with computer case fans -- fun starter project to learn about wiring in series and wiring a three-prong switch, but totally inadequate for cooling the inside of a Ford Explorer!). So yeah, can't speak to how good this is for actual use in ducts, but as a cheap powerful basic fan for a DIYer doing something fan-related, it's a great buy and I'm thrilled I got it. The only way it could be more perfect would be if it had an on/off switch already integrated into the power cord, but that's not a big deal and of course it's not like it advertised/implied that it would have one. It's exactly what I expected, except more powerful. Everything about it seems solidly made and I anticipate it'll last a very long time. I'll most likely buy from this same manufacturer again in the future when I need fans of other sizes.

### ⭐⭐⭐⭐ Not strong enough to open my dampers
*by K***F on February 26, 2026*

The fans work fine, but because they are low CFM, they won't open my butterfly dampers. I had to step up to stronger fans. These aren't terribly noisy, so if you aren't using dampers that require air flow to open, they're a good, affordable choice.
