I just received my ChessUp board, two days after ordering, and played a few games OTB, against AI, and online (lichess). Everything works perfectly as advertised! (I did update the firmware and calibrated as recommended first). It's a bit larger than I expected; maybe thats a good thing. The carrying bag is nice too, just right for the board, charger, and a few accessories. Better quality than expected, and have not had to recharge yet after 6-7 games. The app seems to work great, no issues. I can't wait for Chess.com integration and other promised learning features. Highly recommended!
