The inserts do provide some hassle when changing caps, but that's only a problem if you change them so very often. Also, with Cherry PCB stabs, there are a lot of times when you try to pull caps off that you pull the stab out, which sometimes leads to the wire popping out, so you have to work on getting all those things settled back in. I haven't had that much trouble that people seem to experiencing changing caps with a Costar stabbed board, but then again, I don't change caps all that often.
