the route their used on had to be bolted ground up as there is no access from above and the line too steep anyway so bolts are no more than about 3 feet apart. if a quicklink did fail you'd have a whole 3 feet to fall (scary stuff). we did do silly things to test them before putting them up which was quite good fun and i have taken many a lob onto them without any probs so far and recent visual inspection suggests there ok.
for using as an emergency lower off (ok maybe more like....help i'm too shit at climbing i'll have to lower off from here) i'm sure there fine. but obviously this is just my experience and everyone else may die a horrible death.
