I had the mk2s. They were good except when I managed to run over twigs. The first time it happened I replaced a snapped arm and the second time the arms ripped out of the holes in the guards turning the holes into open slots, but they were still usable. I hardly ever ride off road and never for long sections so I thought this was pretty unlucky.
They put up with a lot of bending eg carelessly loading into a car. I like that the rear guard has an overlapping section near the chainring. However, the front one is too narrow at the bottom: In heavy rain, water sprays around the guard onto your chainring and toes.
