I've been using this regularly for about 6 months, mostly as part of a yoyo/RADS climbing system in tallish pine trees. As a component of that system, it does just what it needs to do: allow pull-through and ratcheting action on the ascent, and a reasonably predictable rappel on the descent. I find that for some of my longer slides (100 feet or so) it gets pretty hot - it doesn't dissipate heat as nicely as a rack does - but if you take your time, or aren't going too far it's a good tool for a rappel. It's a bit fiddly to get on the rope, and it's only slightly more forgiving than the other rappelling devices, but it's lighter and cheaper than other tools with a similar function. Works for me. Desi's comments about rope size are worthy of being reiterated: this is really designed for 11mm ropes and shouldn't be used very far out of that size range.

This is one of my favorite tools. I actually do not own a figure-8 anymore. This is a well designed tool for the purpose intended. It takes a little bit of trial and error to make sure to operate it efficiently and safely. The first descends were kind of jerky but smoothed out as the climber becomes efficient in using the Gri-gri. Make sure to read the instructions included with your purchase and use only the correct size ropes. Smaller ropes will not grab correctly on this tool and can cause a sudden descend. Make sure to hold the right hand on the working side of the rope before actuating the release handle. Very efficient tool for long descends, make sure to slow down in order to reduce heat build up in the unit with possible damage to the climbing rope.
