I've had it for one season now after using normal carabiners for about 6 years. It is a great belay carabiner to use with an ATC. I thought the inner clip was a gimmic, but I really like it. It keeps the carabiner from rotating on your belay loop when the rope is slacked, and normal carabiners spin very often. It's nice to know it's always on its strong axis and the darn gate doesn't get annoyingly snagged on the belay loop when loaded. I don't like fussing with a belay. It's one of those things you wouldn't even notice till you get this. Make sure you clip the inner clip over your belay loop because unclipped and loaded feels awkward. The spring gate is especially nice for the belay carabiner.

It's not so nice to clip into burly toprope anchor points since the clip side is so narrow, but I believe it was primarly designed for belay, and it excels at that.

I thought I'd just buy this one to see if I was missing out with all my 8mm Mammut Dyneema Contact Slings. I'm not. This is more expensive and the weave is more apt for snagging, and the biggest drawback is the sewn connection. It's big and stiff and has no cover like the Mammut,which makes racking more difficult. The Mammut essentially feels like a smooth continuous loop. Other than that, it's the closest thing to the Mammut I've seen and is a close second.

Best sling I've seen and used out there. I've got 3 of the 120cm's for anchor building and long extensions and 15 of the 60cm's as my primary extendable slings (replaced all my dogbones). They are light, very light. The weave holds up great to abuse (no snagging), and the end connection is great (see the pic in past reviews, explained very well). It essentially feels like a continuous loop, which makes racking much easier. My 2yr old slings look brand new despite hard use from the Gunks to AZ to Thailand.
