Not much use as a standard climbing krab (for a start you can't tell which end is which very easily), but a good lightweight oval for pulley use, and probably the best krab for icefall activists to rack a Petzl Spartha knife and an Abalakov threader on, as the knife hangs downwards properly and the krab is large and easily opened whilst wearing gloves, plus the wire gate doesn't freeze up.
Also recommended by some climbers for racking wires on and you can rack one or two extra on these, without them sticking out at awkward angles (though see the point about not being able to tell which end is which above).
Actually designed by DMM as a big wall aid climbing karabiner as pulleys and so on will also hang vertically. The large, shallow baskets provide a similar performance to an oval, while maintaining a bias towards the back of the carabiner to increase strength. Webbing sits comfortably at either end and they work as well with etriers and haul bags as they do on backpack straps. They can accommodate multiple connection points. With a large gate opening and narrow nose the WallDO can be clipped into anything from complicated anchors to tiny pegs.
