Best belay device I've ever used!
I started using my buddy's Cinch a few months ago and am completely sold on it. I can literally throw rope out of the device while lead belaying a partner. You can also belay off the anchor with it. I've used the ATC Guide for years now and it takes too much effort when belaying off the anchor in guide mode or when lead belaying, especially with fat ropes. I also own a GriGri2 and it pales in comparison to the Cinch. I was taught how to properly operate it and have had no problems.
Watch this video from the Trango website to operate it properly. http://youtu.be/lkOVssfihn0
