*by B***B on Reviewed in the United States on August 17, 2020*

Good packaging, all working parts. Little louder than the original fan i had on sidewinder x1 3d printer.comes with long bit of wire. Depending on your printer type/use may have to trim.

    They work
  

*by A***2 on Reviewed in the United States on March 28, 2021*

I used these for fans inside a cosplay helmet to help from the lenses fogging and too help keep me cool, and they do just that.  I have them hooked up to a 3 AA battery pack and they last for a good amount of time.  They are a little noisy and I did have to create a cover to keep my hair from getting caught in them, but that's due to the application I utilized them for and not any fault of the design or manufacturing.
