I own a Lego Mindstorms 8527 set and the display of my little computer finally gave up, which happens to be a known production error. I just had Lego on the telephone and although my computerbrick is about 10 years old!!! Lego is still replacing it without any charge. I can't remember getting such good service before!
Hats off to Lego. Too bad they, in my opinion, screwed up with the Lego EV3 set (A whole lot of processing power, but very little IO's) else I'd bought one right now! Maybe next Mindstorms set. ;)
Totally awesome that they are going to replace it after all this time. We need more companies that are willing to stand behind their products. Congrads to you.
