A larger carabiner that's not that heavy

This is nice for when you want a larger non-locker but are still a little bit weight conscious. It's not the lightest in the market, but it's pretty good for what it is.

Questionable durability

The metal on these carabiners tend to acquire sharp grooves from contact with traditional expansion bolt hangers, like those from Petzl and Metolius. This is not a problem with more rounded edge glue-in anchors.

I used these for my alpine and double length draws while trad climbing. A good price and design. I've used these before this most recent purchase and found value in its prices and durability. Haven't found any issues with it.
