I was skeptical at first but love this pulley, its extremely versatile. I use it as an ascender and bought 2 so I can set them up as a Z-rig (3:1) rescue system without the need for prusiks. I have also used it as a normal pulley as you can lock it into normal pulley mode. It seems really well made and is pretty light so you can carry it with you. I also use this as a lanyard adjust instead of a prusik knot.
