Good

### ⭐⭐⭐⭐⭐ Mighty!
*by A***. on May 12, 2026*

I used these in my mini shoebox greenhouse. They work awesome and really keep the air circulating. Now this is based off my setup for what im doing so judge the air movement your looking for. These are small but also have 3 speed levels and when set on high they could probably left a small hobby drone.
