The cover is really good. Nice and solid. So far I have a Pi 4 and two triples. Both types fit with no problems. The instructions were difficult to follow and not very helpful. I watched a video that seemed to have a slightly different model, but from there I was able to figure out what needed to be done and get it done. The downside is that it's difficult to access the GPIO pins and I'm not sure it would work with ribbon cable connectors (camera, display) without modification. In my case, that's not a problem either. I haven't decided yet if I'm going to use fans.
