Great value

4 October 2016
Great value , sturdy construction .

Awesome screw gate. Highly recommended.

Light and compact, the screw closes really easily. It is the equivalent of the rocklock in a more compact/light size.

Light and Fast

Great little unit, smaller than I expected but a perfect size and light too!

Solid performer.

Like the rest of the positron family, this is a solid and dependable biner that is just the right size. It's reasonably light but not a featherweight. I use them as my standard locker for everything except for belaying with an ATC or a munter, when I want a larger biner.

Great for clipping in

Great biners for general use clipping into culminating points etc and easy to remove one handed with the non-snag nose. Tends to jam when feeding slack to a leader, especially with newer rope.

Keynose for the win

I wish all my screwies were these. I curse every time i get a wire snagged on the end of a non-keynose biner while trying to dismantle an anchor set deep in a crack. Grrr!

very good biner for general use, but not the best for belaying with a atc or something alike. but over all very,very good biner. oh, and it also has a very good gate action and gate strength!

Great light locking biner

A great no fuss light weight locker, I carry a few of these on my trad rack for building belay anchors. The keylock gate is nice feature. Perfect for the job.
