Assisted breaking does not mean hands-free. Make sure you always keep your hand on the brake strand when using any type of tubular belay device, like the Petzl REVERSO, in guide-mode. Produced for Petzl by Benjamin Eaton.
Petzl asked me to create this technical instruction video about the Petzl REVERSO. The Petzl Marketing team handled the storyboard and shooting. I was in charge of editing and even got to be one of the climbers.
