I was in Spain last week with a bloke who has a set. Not sure which particular model - big square soft boxes that hang off a frame. He's used them for a couple of trips to the mountains now, and they seem to be holding together pretty well - more than capable of surviving rattling round the trails on the back of his 690.
I do remember they seemed to take a very long time to arrive after he ordered them, but he was told that at the time and they came when they said they would.
Half the price of the equivalent Kriega stuff.
