Sylvan Rocks Climbing wrote a review of Metolius BRD Belay Rappel Device on November 21, 2007
We got one of these as a gift while on one of our 6 month climbing road trips. Its not the device for fat ropes, but since we only climb on skinny strings these days it works great. If you are headed into the mountains with doubles or a single skinny rope, you will be happy to have one of these on your harness. They really shine on long raps when you need a bit of extra friction to slow things down.
