- Familiarity: I've put it through the wringer
This device is fool proof compared to any assisted braking device out there. No moving cam like the gri gri and it feeds slack out for lead much better than the gri gri. Very slick and easy to use autolocking device. Antipanic feature in the handle is great. The pinch point on the rope is not as harsh as the gri gri, and the orientation for top belay works better than the gri gri.
Overall: better than the gri gri.
