The gear squad from the outdoor blog Dirtbag Dreams recently tested the Grivel Shuttle plaquette style belay device in the Flatirons and Boulder Canyon. The reviewer, Sean Smith is a guide for Denver Mountain Guiding.
From the review: "All in all the Grivel Shuttle is a reliable belay plate. Its design allows for big wallers to combine pieces of kit to cut down on harness clutter, as well as offering the fast and light alpinist to have a solid belay on wet and icy ropes. The multiple orientations create some much-needed diversity in use for a single plate, allowing the leader to adapt to the speed of the situation that is not offered in the average belay plate."
