In reply to jimtitt:
> Hmm. I´ve an original CT karabiner where the hard anodising is worn through to the point it started destroying the rope after one years average use. Feed with a well used 10mm rope is like pulling through mud. We experienced difficulties lowering if there was considerable friction in the system or the climber was light. It doesn´t work in guide mode and you can´t abseil.
Again, I would say most of those things are only the same as for other devices. All belay krabs wear.
All of these devices become pretty unusable with furry 10mm ropes, the Grigri 2 in particular (although it was designed specifically for small ropes so this isn't a surprise, it does say on it that it works with 10mm+ ropes though and it doesn't really).
Never had any difficulties lowering anyone including my very light children (they lower me as well which is a good feature of the Click-up where there is a mis-match in weight).
I have no problem using it in guide mode, although I think the Alpine Up was designed with this in mind.
But I agree, don't ever try and abseil on it - it gets extremely hot!
