I really like convenience of using an external fan with a usb and being able to adjust rpm. I would have preferred a slightly longer cable, but this works just fine. ### ⭐⭐⭐⭐⭐ So Far So Good *by on Reviewed in the United States February 24, 2026* Works great for my little 120mm desk fan kit so far, appreciate the speed control dial. ### ⭐⭐⭐⭐ Does the job. *by on Reviewed in the United States July 6, 2026* Seems to work well.... will see how long it last.
