I like that they're lightweight and compact, but the gate sticks open on a few of mine. You don't want to be run out above gear and look down to see an open carabiner.
Still gave it 3 stars, because lubrication at the pivot points seemed to help, but I'll be a while before I'll trust these little guys 100%.
