I use these biners (w/ a locker) for my cordelette. For me they (along with all the other super lightweight biners) have too small of a gate opening for me to easily rack with them (practice makes perfect?...). Either way, I like having this biner around. I've used them on draws before and they worked, but I haven't done it since--they're just not as awesome as the WC Nitros (or Heliums), but those full-size biners aren't really a fair comparison. Compared to other micro-biners I like this one the most.
