Good for your belay device
It's great for belaying and it's big enough you could use a munter hitch if you had to. A solid piece of gear you would expect from petzel. I'm giving it four stars instead of five only because I took it canyoneering and it got some sand in the mechanism which was hard to clean out till I got back home, so it would not auto lock and I had to check it was secure and help it along the whole trip. Again I was in some pretty fine sand which was getting everywhere, and once I got home and washed it and oiled it, the device was good as new. But for that trip it wasn't ideal
Convenient, easy, safe, really great in the gym!
I am a gym climber at the moment 100% and safety is always a good priority for me in general regardless of where you are. I like the ball lock because it's an extra level for the twist lock. It also helps when you take a friend to the gym, small but devastating mistakes can be avoided like not locking the screw gate. I have no issues opening and closing the ball lock, just takes a few tries to get into being muscle memory. A few of my experienced climber friends have also used it when borrowing my belay device, and found no issues operating it. Honestly it really just comes down to preference with this Carabiner, but the design and functionality are 100% on point!
I'd love to just lose these and be done with em.
I've been climbing for 15 years now and I own two of these- I abhor the locking mechanism and they sit in the house. Beautiful in theory, the ball is difficult to locate and depress with bare hands, let alone gloves. There are some pros to this design, like the impossibility of the rope unscrewing the gate as with a screwgate or traditional twistgate, but in my opinion any such advantage is outweighed by how frustrating it is to operate! It's a shame they couldn't succesfully improve upon the design because the Petzl William screwgate is one of my favorite biners. Do yourself a favor and go with a screw or twist gate William, they rock.
my favorite carabiner
Odd to see this rated so low. I've used it for about a year now and it's perfect. It's the easiest to open and close and there's no way of forgetting to lock it. I can't think of any reason to give it less than 5 starts. I really love that you can see from a distance that it's locked and don't have to ask your partner to double check and watch them tap the gate a bunch of times just to be sure. This is super convenient and perfectly executed.
Green means GO
Once when belaying I had not manually tightened my standard carabiner. Thankfully my partner checked and saw it. The more one climbs, the more one can get too comfortable and complacent with our gear. So I got this one a few weeks ago and LOVE IT. It's much easier and faster to take off and on, has a positive and solid lock once released, and that green button tells both me and my partner that I'm GOOD to GO.
Belaying so much easier
Makes belaying and anything else with the caribeener so much easier as it does not need to be twisted multiple times in order to be opened
Perfect for anchors
I was originally looking for a Petzl William Triact but decided to try this locking style since the Triact is not in stock. I was delightfully surprised at how this is the perfect intersection of usable and secure. It requires 2 movements compared to the 1 movement of a twist lock, preventing accidental friction-based openings. I’m able to open them swiftly with one hand and I used 2 of them to connect my PAS22 to 2 different bolts for redundancy when cleaning a sport climb. I recommend this large, secure carabiner if you need carabiners for anchoring.
I love this biner, I own four.
I find no issue with these, super easy to open. My absolute favorite.
Easy to open, certain to stay closed
My kids and I have been using these since we began climbing 11 years ago. It is simple to grab it blind, open it one-handed without a bunch of twisting, and know that when it is released, it stays locked. It is a simple press of the thumb to release with a quarter turn. It has been used easily by children as young as 10.
Petzl ball lock carabiner
The Petzl Ball Lock Carabiner is a fine carabiner and can be used for a Munter hitch. It is slightly larger and heavier than the original model. For that reason only, I returned it. I did not want extra weight as I would be using it for canoeing.
