I am coming up on two years with my d'addario chromes on my Fender P and I can't see a reason to take them off yet. They just keep getting better with age which, I know is the whole point. It just amazes me having come from rounds for years and changing them out all the time. They are my first pair of flats I ever purchased and might be my last as long as they keep doing what they're doing. They also get me quite a few compliments at gigs.
