These little fans work great I prefer to use them for my home built reptile incubator to circulate air around inside and keeps the temps even through out

Works well. No issues.

Good quality.

Good quality fan. Well worth the money. I have it running 24/7 with no incident. Quiet too!

This is a 220v fan with a 110v plug. It looks nothing like the product described, and doesn't even function as a fan at 110v. Another reviewer raised this complaint 7 months ago and the seller is still sending out paperweights.Seller should be banned, this is fraud.

I'm getting ready to do 3D printing with ABS and it's warned that ABS printing needs to be exhausted through a hepa and carbon filter system. So I got this fan to draw the enclosure fumes into a filter system I designed. The fan works excellent for this and the variable speed enables me to better regulate the airflow and temperature inside the printer enclosure. Very happy with the perform of this fan. Just hope it lasts.

I actually used just the power supply portion with variable speed control and NOT the fan itself. I had a custom project to create a custom room fan for my senior mother. Her 'go to' fan finally broke after running 24x7 for about 2.5 years. We tried purchasing replacements but they were all to 'noisy' for her - so she could NOT sleep/nap with any new ones we bought, and we purchased 4 of which we could only return 2 of them. So I purchased this along with 2 brushless ThermalTake 200 mm computer case fans and created a custom grille and frame and mounted on a cheap tripod and now my mom has the perfect fan. Even at top speed, mom is sleeping without any issues. Used a remote controlled outlet and now mom can turn on and off as she likes, but mostly the custom fan is running 24x7 again. And with brushless fans computer case fans, I can sleep at night no sparks will fly and no fire will happen in the house over the carpeting in her room.

I can't even understand the physics of how they built this so poorly. Running at full power you can barely even feel a hint of a breeze coming from this - I am absolutely befuddled by the 5 star reviews here
