Great in small sizes
I use the three smallest sizes (00, 0, 1) instead of C3's. I love the light weight, and I think the trigger is a lot easier to use on such a small cam. I have big fingers, and it can be tough to place or clean small cams. The design allows cleaning by pulling on the trigger with a nut tool if needed. The cams hold well, though as with any very small cam there isn't a lot of surface area.
