Review on Hephis Bottle Opener Carabiner Chains by Mario Beckwith

I've been using carabiners (not climbing) to store keys for over 15 years and the loop on it always loosens or dislocates after about a year or so. I stumbled across this one and decided to give it a try. Have been using it for a few months now, it's built like a tank and the bottle opener is solid. I wish it was a little less edgy aesthetically, but the colors are beautiful and functional, this thing couldn't be better. It was very convenient to keep my car keys on the top ring and my house/work keys on the bottom ring.
