SUM - faders
Review by: aefavant, 2007-06-20
Great device! Most people would prefer grigri, but gosh, that sucks!
SUM can be used with both your hands equal, is smooth and won´t fail as grigri when you catch the lever by accident.
Heavy? ony if you´re too weak
Bad point? well, the manufacturer let´s it stand quite clear as to rope width. If you try and use an old 10.5 it will get tricky to handel the rope. otherwise, I will never use grigri again :D
