Great size
Great pulley that fits very well into my swift water PFD. I also carry two more in my class 3 harness. Simple to use as expected. Well constructed and accommodation of most size carabiners. They are lightweight and compact which make adding them to your kit seamless.

Simple and cheap
Works as advertised, and is by far the cheapest rescue pulley option on the market. Hook a carabiner through both plates and you're good to go.

Perfect for Crevasse Rescue
This is my second pulley, I liked the first one so much. The best feature is the “wings” that tend to your prusik knot. This is very useful as a progress capture in a hauling system. Considering it weighs so little, it’s a great piece of kit that lets me leave my ascender at home and travel fast and light on the mountain. The hole is large enough to fit all of my carabiners as well.

Good quality, light weight.
Great prusik minding pully for rigging mechanical advantage rope systems.

Small and light weight.
I also bought some locking carabiners with this, but the locking mechanism is too big to fit through the hole on this pulley (http://www.amazon.com/gp/product/B001A9JFT2?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_11)You can still use them, but it makes them a bit inconvenient.

Una Polea Super compacta
Me pareció genial la posibilidad de una polea tan compacta, con un buen rendimiento, para mejorar, que sus placas laterales sean un poco más firmes

Very light
Very good. light and small. I am using it to tend a VT prusik (Valdotain Tresse) on 11mm static rope
