Very flexible in terms of what it supports. Somewhat difficult to assemble (maybe they fixed that in the latest release). Works pretty well. But honestly it’s going to depend on what printer you are using it on. When I did it on the ender 3 it didn’t really make a big difference, that printer is slow and additional cooling wasn’t needed. If you are printing filaments that benefit from lots of cooling and are printing fast it can be helpful to get multiple 5015 fans running.

One nice thing is that you can choose some fans that are bigger (4020 and 5020) and run them at lower speeds to reduce noise.
