Was I sceptical? YES! Am I happy with my decision? YES! My climbing partner and I have been using the Grigri and were pretty happy with that until now. This has a simple design that just works. I do suggest you watch the video of how to use it and practice, but after you've done that you'll never go back to the Grigri. When a climber is leading you just hold it in your hand at the right angle and watch it feed super smooth. If a fall takes place it will lock up quick and perfect and your hand naturally grabs hold of the brake end of the rope. I don't recomend using it as a ascender, but I had to at one point first trying the grigri only to find it impossible for how I needed it to work. The cinch did it like it was designed exactly for that! I'm telling you it's like magic. Small, light, WORKS!
