Echoing what dag said, this is more of a novelty if anything. The width of the key ring itself gets items with smaller keyring holes stuck (ie. gym membership tabs). The "freekey" system itself is also flawed, as because the keyring has a bump to accommodate easier opening and closing, keys will get stuck at that wider spot, if this makes sense. I ended up just using the smaller keyrings to attach my items to a normal keyring.
