(+) Very light hardly interferes in your pocket
(+) To handle cable sheathing pleasant
(+) Flexible I can rope easily as small wrap (eg, diameter 10 cm) in order to put them in his jacket pocket.
(+) Ability to form two loops
(+) Lock can be pushed along the cable and must be attached to the rope before you can adjust the digits. This is important to the loop to keep as small as possible to the fast breaking with any lever to complicate
(- -) To adjust the lock combination will need to make a small screw to 90 °. Mechanism is rather imprecise and the screw can be easily damaged. I expect that the screw is not more than a few setting operations survived.
For me strong buy recommendation
