Suiper easy one handed use
not great on bolts...

This biner is super easy to use. Many auto-lockers are a little difficult to use one-handed, this one is easy. I've never had an issue EXCEPT when clipping into a bolt hanger. I was curious, so i clipped in with the gate facing the bolt head. I was able to manipulate the biner in such a way that the bolt head would engage the slider and unlock and open the gate. However, I was unable to remove the biner from the hanger without the gate snapping shut and locking. As a result though, I always clip into a bolt with the gate facing away form the bolt head.
