Great for knee ascender

I got this to make a knee ascender and it works really good. They have it cheaper than anywhere else and it looks like good quality. I think it might be made by Kong because it looks exactly the same as my friend's. It runs really smooth up the rope and the lever is easy to flip open if I need to get the rope out to move around while in the tree. Shipping was fast. I got my order in 2 days. Free shipping too because I ordered some pulleys, carabiners, and prusiks too. Everything is good quality. Will order from these guys again.
