Dave did a good review of the G20 here earlier:
Dave's original crampons ended up at the factory after a more than "full use" imo and were replaced free of charge. Although I would have assumed by the condition and the climbs they had been up that Dave had simply worn the G20s out. In other words I was surprised they gave him a new pair to replace the is shattered pair. Nothing lasts forever at the high end of this sport. Although Dave's G20s were certainly trying!
Contrast that to a year long debacle of broken crampons over at BD. Grivel not only recognised there was a problem but engineered a fix in less than 5 months. Something to think about next time you need new gear. I know it turns my head. Click on both pictures to get a better idea of what went into the full story here.
