I trialed this before I bought a Petzl I'D (which is less expensive). It works great and is extremely adjustable, but it weighs a ton and is kinda complex. Took me a while to get my head around all the bits and bobs before I felt like I could try it out.
For large (rescue) loads, there's nothing that compares. I've seen tests that have all but destroyed all of the belay devices, except for this type of device from SRTE. Importantly, after the most strenuous of these tests (11kN shock load) the device could still be used to lower off. All other devices jammed under the same conditions.
