This carabiner was bought with no intention of use at its full capacity or anywhere near it as I do not climb (unfortunately). It's uses have though been able to secure many heavy and loose items in vehicles for security and use as an anchor point at many other stages. I would have no qualms in using and trusting this version. I have used this to hold myself of the ground with dog leads and no issues. Basically it's THE manly keyring that can't be beaten. A smaller version would be perfect but that's not it's proper use. I love it.
