Here's what other sites are saying:
The aptly named Mad Rock Aviator Belay Device wants to help take you to new heights. Built with aircraft-quality aluminum, the Aviator features auto-locking capability for when you're sketched out on a ledge while belaying your second. An ergonomic fin helps you control friction and braking speed during your belay or rappel, and the unique removable spring keeps it from locking when feeding the rope.
