No, it's just in your mind. I bought in excess of 24 CB sets within the last year and a half, and what isolated flaws (as in: very few) there were they replaced without fuss. Some have complained that other retailers are not so keen on making amends for mistakes.
Going on 2 months awaiting my replacement bishop. I'm not complaining - just saying.










The new Dubrovnik set by Chessbazaar seems better than Staunton Castle’s and is also at much lower price.
As a happy owner of the CB 3.0 set, I still think these SC pieces look to be a step above, especially on the knights. It's really great to have so many good options.
