All the features you need in a nice light package
Impressed with this design. Nice and light, makes it easy to go up and work on tough cruxes or get some photos of your friends. The handles might be on the small/uncomfortable side of things if you're doing a lot of jugging in a day but for my use cases it's perfect.
Love it!
I was really nervous getting this at first especially since I am not left handed, however the way they designed it made it super easy to handle with your non dominant hand
Classic Must Have Kit
Classic piece of kit, I use it for my top rope solo setup. Makes moving on the rope very easy. The large clipping hole is a nice feature over other brands.
Better than Petzl
That's right, I said it. I think these ascenders are the new gold standard. Light weight, easy to operate and the index finger action is clutch.
Amazing!
I rigged a rope access photography using the ascender + grigri and it grips well enough that I trust my life with it! Super so far
Does what you need it to do.
Fairly lightweight, easy to handle. I do wish you could clip two carabiners into the bottom, but not a big deal.
Much better
Much smoother operation and trigger pull than others
Great
This is really nice the triggers make them amazing
