In reply to HeMa:
Hi folks, for single pitch I would agree that a clip stick is a better buy, but for multi-pitch I can see the benefit.
As to the difference between the Prog and the Panic - no idea!
There's an EpicTV infomercial on YouTube that tries to explain...but I still don't really get it.
I think the point is that the Prog is more like a locking carabiner, but the Panic also seems to lock the wiregate under load so....
There's an alternative (cheaper) knock-off called the Tricky...

It has the USP that you can fold it in half for clipping onto your harness so less likely to get in the way when not in use.
Having said that think the idea with this one is that you are meant to replace it once you are past the tricky move and not just leave them in situ and climb past it. Not sure if the Kong products are the same.
