Review on 🌬️ O2COOL 5 Inch Portable Fan: Battery or USB Powered, Ideal for Travel, Outdoors, Camping, Car, and Office - Compact Foldable Design with Adjustable Head for Targeted Airflow - Black by Reginald Sealy

This fan was the perfect solution for me - at least that's what I thought. I needed a fan for quiet, easy airflow. The fact that it was USB or battery powered was a bonus. This gave me excellent service for several weeks. Initially, the low speed was unstable. The speed depends on where it is placed. I wasn't sure why but it wasn't a big problem since I left it in one position. But this morning it stopped working. I've tried this with both the USB connection (I plugged another device into the same port and it worked fine) and with fresh batteries to no avail. It's not worth sending it back as the return postage costs almost as much as the original cost. But now I'm back where I started - still need a small reliable fan.
