Great Little 8!
I bought one of these a few years ago to add to my collection of rappel devices for when I take people rappelling. The only complaint I have is that it gets hot pretty quick for aluminum. My really old KONG 8 hardly gets hot at all so I was a little disappointing in this 8, but over all it's a good little device.
If you are looking for a rappel device for canyoneering, stay away from 8's! They twist the rope and make it hard for the next person to rappel. I would recommend the Wild Country VC Pro II ATC for pretty much everything!
