REVIEW: DMM Mantis belay device

OK, there's not a lot to it. But it's light, it offers loads of grip for secure belaying, and it works smoothly on a wide range of rope diameters... what's not to like? If you're after a simple, effective and versatile belay device - and if you don't require the option of a guide plate mode - then the Mantis has to be one of the best choices currently available. I take mine everywhere.
