Review on High Performance SXDOOL 135X135X25mm 12V 0.70A DC Brushless Cooling Fan - Ideal for PSU Power Supply, PC Case Chassis & Efficiently Cools with High Speed CFM by Paul Gravely

I wanted this fan to replace the PSU fan. When I open the package, the mounting screws and something else fall out. Something else was one of the fan blades. The packaging it arrived in was undamaged so the blade just fell off in transit. How is that even possible? I have to assume the quality is pretty bad although I'll never know as the fan is useless. Revain refunded my money but I still don't have a fan for my PSU. This was my second attempt to solve my problem.
