Customer Service Beyond Expectation

First of all, the chess set is beautiful. I gave it to my son two Christmases ago and he plays it constantly. He is very proud of it. So...when our dog captured the pawn and chewed it, my son was bummed. I contacted Chess Central and they said that they would work on it. I totally forgot about it and figured I'd never hear back. Today, guess what arrived in the mail? The black pawn! My son actually did a little jig. Thank you, ChessCentral.

This is by far the most impressive chess set I've ever seen!!

Now you have to know up front when buying online I generally look at the three star and lower reviews, so I ordered this set with a lot of skepticism, just sure something was going to be FUBAR,...... Boy was I wrong!! I got the set and carefully un-packed it and was just amazed. It is PERFECT!! Seems that all the every flaw that had been complained about in the three star and less reviews had been addressed by the manufacturer!! So being eager to show it off and being a good ole boy, I invite my buddies over and we all set out on the porch {now that the weather is finally getting nice out} and play from noon until sunset. I enjoy all the compliments this beautiful the set gets, and everyone loves to play on it!!

I've shopped at ChessCentral three times now, and twice I've had questions about a particular product. I don't know much about chess software. Anyway, I was shocked to receive detailed answers later that same day! I mean, who does that? Shipping was fast and well packaged. All in all, a great chess website.
