Review on Compact 4 Inch USB Desk Fan: Powerful Airflow, Quiet Operation - Perfect for Cooling Desktops at Office or Home by Nick Walsh

I bought this small plastic fan together with the very nice metal fan. This guy is on my floor blowing cold air out of my vent and into the room. It's been on almost constantly for months, I've taken it apart twice to clean it and even accidentally kicked it, but it's still working solidly and quietly! Nice little metal that sat on my desk and didn't move much. became loud and annoying after about a month. I will buy another one to replace it lol.
