Good BD quality
A hard-to-use and inexpensive solution, the roller lock has been able to open once every couple of times. Worked well in the threshing string drive system.
Light weight good
Good and inexpensive sealing rings e.g. anchor building. On the downside, symmetry makes it harder to see the gate facing the gate open.
The basic carabiner runs its course and is not spoiled for price
Good carbine for hammocks
Classic; did not come for climbing use and was looking for an exceptionally reduced and symmetrical / oval carabiner, these Black Diamonds are probably the only ones in the range.
Screwgate so far feels good, if this lasts so the button choice was.
