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.
Review: Love this thing - We live in Arizona and our garage gets really hot in the afternoon due to the heat from the uninsulated attic above the garage. I took some plywood, made a new access door into the garage since the existing one was flimsy drywall. Then I cut out a circle in the middle of the access door a little wider than this fan. Then I used 4 "L" brackets to attach the fan to the access door. I cut holes into the side of the fan housing and used my rivet gun, then attached the other end of the L bracket to my new attic door. You can use short sheet metal screws but I wanted an excuse to use my new rivet gun. Then I plugged this into an outlet plug (Kasi) so now I just use my iphone app to turn it on/off and I can schedule it. It's mildly loud, but not bothersome by any stretch. We have a 3 car garage and it moves a lot of air - so much that I can see the garage door move inward a bit when I turn it on. So overall, I really like this and it's pushing the hot air back out of the attic through the gable and roof vents to now my garage isn't over 105 degrees anymore in the morning.

### ⭐⭐⭐⭐ Works well, vibrates a lot and is noisy.
*by B***N on June 18, 2024*

Installing this fan was super easy, as well as getting it powered up. At full speed this fan is quite noisy, but my main issue is that it vibrates A TON at full speed. I bought an external fan speed regulator switch so I could slow it down to eliminate the intense vibration. This helps with vibrations and noise level, but of course provides worse air flow. While the fan is very powerful at this price point, it would be nice if the fan blades were balanced.
