David Burberry wrote a review of Petzl Owall Carabiner on June 2, 2011
This is one of the few keylock ovals on the market and the only one sold on backcountry.com. I bought it for use as a racking biner for my nuts. The oval shape and keylock nose make this perfect for this application. The down side to this biner however is its wieght. At 68g it is more than 2.5 times heavier than the 26g biner I use for each of my cams. It also makes it the single heaviest non locking biner I own. Thankfully I only use one.
