Ryan K.wrote a review of Petzl Ange L Lite Wire Gate Carabiner on August 26, 2013
Familiarity: I've put it through the wringer
These are nice and light and handle extremely well. Thicker gloves were surprisingly not very awkward (to me anyways) with the short, single wire gate. They also have a higher than most open gate strength rating. The shape is different than anything I have used before and they have quickly become my favorite carabiner.
However, they are not cheap. At almost $12/biner, there are options that are half as cheap and better than half as good. If you have the money, I highly recommend these if you want/can afford these, however, I'm not sure they are worth their $12 price tag.
