The fans work great in my costumes. The fans kept me nice and cool. I love that the cord is long, so I could put the battery pack, I connected it to, in my pocket.

Moves a lot of air for their size. Quite on low setting. Loud on med-high. Grate for keeping amps or electrics cool for best longevity and proformace!

This works really well in our RV fridge. It circulates the air from top to bottom and it’s very effective.
