We used these for podium computer setups where rack and cable runway real estate is at a premium. The slim design is great since the cables have to fit through tight openings with other cables crowding them out. I think I mangled one cable when trying to plug it into a switch in a tight space at an odd angle, but that was my fault. I was gripping it by the cable behind the boot, rather than pushing on the boot itself. The boot is a decent size and has enough length that you should be able to jam it into difficult spots without making the mistake I made. Other than that failure, these have been working flawlessly.
PROS: Slim design, flexibility, good boots
CONS: Might be easily damaged if manhandled a little too much
