Got one for an emergency, but wouldn't use it everyday!

It's a great piece of gear to have around in a pinch! works a charm, you have to use it on an oval carabiner, recommended is the petzl OK oval, which is a great biner. I've had success on other ovals though. You really need to keep an eye on it during use, because there is a possibility that the rope will slip off of the pulley (not a safty issue, because the rope is still going through your biner.)

All in all i really cool little trick to have in your pocket!
