It's a good screw carrier. While not perhaps as sturdy as similar one from BD, it's strong enough to cary up to 6-7 screws. I like Petzl Caritool better than Black Diamond Ice Clipper because it has a long "tongue" that keeps the clipper better in place also vertically... this true even in case you have a BD harness that has clipper slots. The only problem I've experienced is the "stretching" with a heavy screw load - as a result Petzl Caritool is currently my screw carrier of choice.

Best iceclipper out there IMO! I always have 4 of these on my harness when iceclimbing, two on each side which I rack all my icescrews on, the tongue makes them stay put and the small "fin" on the top means you can flip a couple of screws up there to get one that sit further in.

This is the best screw carrier I've used so far. I have four of these on my harness during winter, and keep two on my harness for rock climbing in summer. I had the BD ones for 4 years, but I found they twisted on the harness and did not stay in the same place. I do not have specific clipper slots on my harness. I tried one of the Petzl ones and found that this problem did not happpen due to the plastic tongue, so I replaced all my BD ones with Petzl ones. I find them easier to use in winter than nomal harness gear loops, as they stand out more and items without carabiners can be safely clipped into them when wearing thick gloves.
