Familiarity: I've put it through the wringer
One time, at band camp I used this . . . oh, I probably shouldn't continue as this is a family-oriented review. Out at the crag, or in the gym, or even at the local coffee shop, the BD ATC Guide looks extra swank dangling off your gear loop. Pair it with one of those locking carabiner thingies and bring your milkshake to the yard. Give it to your belay monkey to catch you on the first pitch, then steal it back and send that poor sucker up the second, sketchy, chossy pitch with confidence.
