I wanted to see how practical it would be to mount my Ubiquiti USG-3P to the DIN rail in my small rack. It actually works pretty well- the mounts are long so you need a ton of clearance below the rail to snap these in, and if your DIN rail isn't super sturdy (mine isn't), then it may wobble the rail a tiny bit. I'm not sure if I'll keep using these, but I thought folks might find them useful.
