Review: Fantastic - PWow....ordered these to put behind my ps5 ans xbox s.....can't believe how good they are....so quiet...honestly they are virtually silent...I've attached them to a piece of wood and they work fantastic....so cheap....highly recommended
Review: Good little fans - For the price I was expecting at least one of them not to work (as usual for cheap stuff like this) but they all work fine. I use them to provide air circulation for growing plants in a confined space and all four together work great. Not exactly jet engines but all provide enough airflow to keep stems nice and strong and prevent stale air.

### ⭐⭐⭐⭐⭐ Good little fans
*by S***N on 21 June 2024*

For the price I was expecting at least one of them not to work (as usual for cheap stuff like this) but they all work fine. I use them to provide air circulation for growing plants in a confined space and all four together work great. Not exactly jet engines but all provide enough airflow to keep stems nice and strong and prevent stale air.

### ⭐⭐⭐⭐ Vibration
*by D***Y on 3 June 2026*

For the price they are great, but they do vibrate so not as quiet as expected. But they do flow air. I mounted mine blowing down and that is their quietest position. If they blow horizontally they are louder. Blowing upwards there is a high pitched whine. But for the price I am not complaining and the USB connector is a great benefit.
