Solid little guys
These are great little cams. The combination of flexible stem and extendible sling means they'll basically never walk, and the flexibility also makes they easier to squeeze into tricky placements. I'm honestly not sure why these guys aren't compared more with aliens, it seems like they have all the same characteristics. These are all great things, but they get four stars because the flexible stem will potentially reorient them when fallen on in vertical cracks, thus they won't catch as quickly, and could pull out. I think the horizontally flexible, but laterally rigid stem on the c3s is the best system out there, but I'd still take these over c3s because of the four lobes. They are about as confidence inspiring as micro cams can be.
