They work like they are supposed to. When the wire gets offset after a fall/load they are easy to reset to make them staight (I like my gear LOOKING good to :)) I've taken falls on a few of these now and they held me in. Also have used them as anchors. Only complaint is that they seem a little soft. After pulling them out of the rock on a fall/load, there seems to be some grooves in them that worry me, but I'm not an expert and I've been told thats normal.
