Love this ultra-light carabiner, and I see that it's on sale at REI for under $6 each. Typically it's about 8.50+ on most sites.
I use these almost exclusively, and they really are ultralight at 27 grams. Hard to go back to my others (e.g. Black Diamond carabiners at 37-44 grams) once I slap a couple of these on my 'mocks. The difference sounds infinitesimally small until you hold a pair of each in your hand.
Just wanted to make everyone aware of the sale. Enjoy!
