One of the most versatile, super bomber, and idiot proof belay devices. I love how it handles my skinny 8mm rope for canyoneering all the way to my fat 10.5mm for sport climbing. Its light enough I don't really notice it on my harness. I've had both the older style and the newer style and can say that the weight difference is noticeable. If you have an old ATC and are thinking about upgrading DO IT! You won't regret it. The mini Pearabiner is solid and a great locker but a little smaller than I prefer for a belay biner. This package is a great deal with the best ATC around.
