DGT North American Chess Game Timer - Digital Chess Clock for Tournaments & Practice - Perfect for US Chess Clubs, Tournaments & Home Play

I like this clock quite a bit, but ...My DGT North American broke, which was a simple mechanical problem where a button wasn't registering. I had trouble getting warranty service for the DGT North American because the manual says to return it to the place of purchase for warranty repairs, but the seller would not accept a return after 30 days. I was able to fix the problem by adding support underneath the circuit board which had come loose on one side. With the DGT North American, there are no screws holding the circuit board in place, only a couple of thin plastic tabs, and that was the problem.There is a Chinese knockoff of this clock that I like just as well. It is cheaper, slightly smaller, and has different settings.
