David G.wrote a review of Petzl Reverso 3 Belay and Rappel Device - 2011 on January 5, 2010
I still think there are ways to improve belay devices but I don't know what they are. Feeding rope is easy but not perfect, taking in rope in "reverso" mode is a solid tug, but consistent. I think it's a great all-around do-everything belay device. I use it pretty much everywhere other than the gym and really like it. Grab one.
