Love these cams
These cams have an extremely flexible stem that, so far, has held up to a fair amount of abuse. The #3, #4, and #5 are my three smallest cams (the #1 and #2 aren't quite strong enough for my free-climbing head game), and I trust them even when I'm pumped and ten feet over them. The trigger action is smooth even in the deep placements that you can get with these. The #5 is about the same size as a C4 .3, maybe just a little smaller, so they compliment my C4s nicely. They place quickly and solidly, and the doubled sling extends the piece nicely. Also, these are not a clunky as their tech-friend brethren.
