WOW! I must be the lucky one. My CH pedals have worked for over 8 years with out an issue. They must have screwed up when they made mine! 
Like anything made, it's possible to get a "lemon" however I believe that CH has an outstanding product that lasts a long time.
I agree, Every product has a lemon or two - I bought a set of Rigid power tools 3 years ago that had some pretty harsh reviews, people complaining about either being to loud or break's easy - I've done everything from drop the batteries in a septic tank, off a roof - and nothing has broken yet and everything works great.... plus the lifetime warranty is honored in every way that I had a damaged tool.
I only wish some of the joysticks and pedals had this kind of warranty, one reason I went with the Thrustmaster Warthog, it comes with a 3 year warranty and I bought a 3 year warranty on top of that for $50, giving me 6 years of security.
I guess it comes down to personal opinion, I had a Saitek Joystick and found it to be complete garbage, this is my biggest concern going with its pedals, might be leaning more towards the CH Pedals.
