These definitely feel tough! Locking mech is easy to use single handed. The weight rating is quite a bit lower than most carabiners comparable in price. In the price range, other steel locking carabiners can have 20-30 KN. I love these things, but I think they’re slightly overpriced.
Leave a comment and let me know what you would use a carabiner for! I need some creative ideas of what to do with these!
