In reply to Alpenglow:
I have one of those, but what looks like an older version, which had a wire on the back instead of that orange strap. Pic here https://www.summittosea.co.uk/climbing-mountaineering/climbing-equipment/pe...
I've found it to work just as well as normal ones tbh, for some reason lost in the mists of time I have one even though my harness has the clipper slots so I get a direct comparison when I go ice climbing. If not wearing very much the wire is a bit uncomfy, but when ice climbing I'm normally wearing enough that's not a problem.
One pro is that it's really big in comparison with the normal caritools I have, so holds loads of screws.
No idea how the orange strap version compares, sorry.
