this is an essential in the climbing world today!easy to operate and safe as all get out! it even has instructions for the new kid! works great on my 11mm maxim apex rope and catches every slip-up and never slides like the petzl stop! it's relatively small and will last many climbing trips! it's the only piece i trust my life with! also it's super versatile, check out some youtube videos about it's uses, for there are many!
get it! you won't regret it!
