They are the worst! My eleven year old daughter wanted one of these this year. Her birthday is right after Christmas and she got her grandmother to get her one by combining birthday and Christmas. It didn’t work correctly, it sometimes can’t figure out where it will move a piece whan it removes them from the board and has dragged pieces through the front row of pawns on the side of the board so they have to be reset. It often misreads the square she moved to and captures it from a square she hasn’t placed it. There are other problems and they never had ANY intention of making it right.I called customer service and they kept making excuses about how they would help as soon as they were less busy. As her 30 day return neared we tried to return it but the 30 day return is also a scam.Now I am making it into a piece of art and will display it at a friend’s game store. I have already dissuaded three people from purchasing one of these pieces of crap. My art will be REALLY BAD for their business. Apparently they can’t help me either fix the defective chessboard I have or let me return it because I don’t have a relationship with my Mother-in-law but allow my daughter to have one. They could not find the information when I sent a photo of ALL THE INFORMATION (serial number manufacturer date and all that). Stay away!
