FresKaro UIAA Certified 25KN Auto Locking Climbing Carabiner Clips, Twist Lock, and Heavy Duty Carabiners for Rock Climbing, Rappelling, and Mountaineering, D Shaped 3.93 Inch, Large Size, Black

Not going to lie, didn't really think about it when ordering but trusting your life to unknown names gets a bit iffy. I got the 3 pack and a few other Amazon specials to do my own tree work. 100% bought the wrong harness, the rope was a bit sketch compared to the more known names that cost 5x, and then there was these biners. Granted I only went about 30 feet up, and I was doubled up on the biners during the actual climb but they held my "larger than the average arborist" size + tools plenty fine. Did all my equipment tests like 2-3 feet off the ground in the beginning on a single biner, had no issues for what that's worth.For the second tree I had gaffs, so one biner on each end of my lanyard and the third on my secondary cinch line, again no issues. I even did a practice gaff out a few feet up just to test the theory, dropped all my weight on the single one on the cinch and it caught me with zero issues.Again, not entirely on board yet for daily use, would probably still go Petzl just for peace of mind, but I am keeping these in my Army kit now for the rare situations where I might have to climb on the job, I would be confident using them doubled up again with no real worries. For anything fall prevention, 100% confident in it for that usage, bucket work, roof work, etc.

Works good quality great

These are really nice! Come in a sealed bag, which could almost be reusable- if you didn’t have to cut it open (not press and seal)

Normally when Chinese company's make something they make sure you know that with china on packaging and product,but when it comes to something involving safety, they get very creative because nobody will trust the product.and in this case they try to make you think its a euro company making these with that euro look to the advertising...very creative. But they are made in china.Now i'm not bashing the product....its very good and i'm sure it will pass testing for the rating, as its made of 7075-T6 aluminum cold forged....pretty hard to go wrong here.In any case i don't think you'll see any reviews here stating "I was killed today when my carabiner failed"

Fast delivery and great product

They are built Incredibly strong ,Highly recommended

These did not fail during climbing, so that allowed me to be here to write a review! I have not taken a hard fall on these, but I have hung with full body weight on them many times. Rated, easy to operate one handed, easy to see that the safety “locked”. Good design. Much less expensive than the “name” brands with comparable weight. I would buy them again!

Fast service, nice product.
