It's made by an Italian firm, Alpine Technology. Rock and Snow has them, I think...I originally asked them to order one for me.
It is an assisted-locking device, which makes it totally different from Reversos or other tube-style gadgets. With today's thinner ropes, I think assisted locking is the wave of the future.
Unlike other assisted locking devices like the Mammut Smart Alpine, this one feeds rope out perfectly with virtually no catching. It also has a non-locking mode and an upper-belay-off-the anchor mode. It's just a better mousetrap.
