Review on 💨 Easycargo 2-Pack 40mm USB Mini Fan: Quiet and Portable Cooling with Multi-Speed Control (45x45x23mm) by Kate Johnson

I bought these fans for growing plants to increase airflow. With small suction cups (not included), these fans can be positioned anywhere and work great. A low hum, but not very noticeable. The plant lighting and watering system works on an automatic timer and unfortunately does not turn on automatically with my home timer due to the multi-speed controller. I suspected it's possible, but I'm still happy with the fans because their small size is perfect.
