This is going to hurt. Virtually all my carabiners are Heliums and I purchased a few more since July 2012... needle in a red haystack.
Most of mine are Heliums as well. But only 5 of them were purchased after July 2012 - at the end of September, actually. Fortunately those 5 aren't from the recalled batches.
Just got a phone call from Mountain Gear. None of mine are affected. Also, I didn't know DMM makes WCs crabs.
