Good

First one I ordered was the incorrect size, but I got a replacement and now it is great!

It's really good

Love it! I always used Lian Li fans in my PC builds. Never gave me any issues. For the wireless variant, make sure you buy the wireless controller in order for it to work. Single packs don't come with it. The L Connect software is a little buggy at times.
