If you want a big biner that stands out (not from other people's racks, because everyone has one) from other companies' biners, this is the one. Omega Pacific makes great products, strong, and this is no exception. Has a really unique design that allows for a huge gate opening, if you want to carry bundled cordelette, and a rounded top so your belay device doesn't sit on the top of the spine, like most others, really comfortable.

In spite of its great function for most uses, it only gets a 3/5 stars because it doesn't have a keylock nose, which doesn't hinder me at all, it actually helps sometimes to hook chords, but that's the standard nowadays; and 2: the diameter of the metal is so big, when using a gri gri, it feels like the two are grinding at times, and that makes me nervous.

One plus, the screw lock feels more sturdy and long lasting than others, for aluminum.

Cant say enough about how great this thing is as a belay Carb. Massive gate opening, not too heavy, very smooth on belaying.

Possibly the best belay/rappel biner to ever come along. When I learned a rappel onto a rappel anchor technique using a two strand munter, the superiority of this biner became immediately apparent.

This reflects my opinion of the screwlock version only. I do not trust or use twistlocks.

Great carb. Esp for Scottish winter. Why can'twe get them in UK :(

Buy far this is one of the best pieces of equipment I own.It's stupid strong,the screw covers the entire latch and the best feature is the WIDE gate opening due to the gate swinging to the side a bit.This is the only beiner I use to belay.
