So, let's talk about these FVW Auto Locking Rock Climbing Carabiner Clips. As an outdoorsy guy, I can appreciate the heavy-duty construction of these clips. They can certainly handle some serious weight, which is great if you're trying to secure your gear while out in the wilderness.While these carabiner clips have some positive features, they also have some drawbacks that should be carefully considered before using them for rock climbing or other high-risk activities.First, let's talk about the positives. The FVW Auto Locking Rock Climbing Carabiner Clips are indeed heavy duty and have a high strength rating of 25KN, or 5620 pounds. They are made of durable aluminum alloy and are well-suited for use in extreme outdoor environments, where strength and reliability are essential. The auto-locking mechanism is also a great feature, providing extra security and peace of mind for climbers and other outdoor enthusiasts.However, I can also understand the concerns that others have raised about the weight and auto-locking mechanism. If you're carrying a lot of gear on a backpacking trip, the extra weight of these carabiners can really add up. And if you're trying to quickly attach or detach something, the auto-locking mechanism can be a bit of a hassle.But let's not overlook the everyday applications of these carabiners. They can be useful for securing things to your bag or belt loop, and the rugged design means that they can handle some serious wear and tear. And even though the auto-locking mechanism can be a bit finicky, it's also a safety feature that can help prevent your gear from accidentally falling off.So, overall, I think these FVW Auto Locking Rock Climbing Carabiner Clips have their pros and cons. If you're planning on doing some serious rock climbing or backpacking, the heavy-duty construction and auto-locking mechanism might be worth it. But if you're just using them for everyday applications, you might want to look for something a bit lighter and easier to use.I hate to beat a dead horse but the Auto Lock feature, I mean, I'm sure it's supposed to be a cool feature, but have you ever tried to use one of these things with gloves on? It's like trying to type with boxing gloves on, it just doesn't work. And even if you're not wearing gloves, these things can be a real finger workout. You're gonna need some serious grip strength to get them to lock and unlock.

using these for safety harness for climbing on my roof. Going to use a Prussic knot to keep me from falling off the roof, these will be connected to my safety harness as a secondary point. I have a regular safety device, but TWO devices are better, as I'm 60 years old, and probably have no business going up on my roof to repair shingles, but I'm going to do it anyhow.

Good price. Item arrived on time. I like the multi color option.

Useing it for horse lead. Works great.
