The ChessUp2 board definitely out classes all its rivals. The fact that it's wireless alone is very special. Hours of gameplay without recharging and with the App ,the ability to analyse your game and see what each move meant . The evaluation bar is another great innovation. The box came perfectly packaged from Europe, with no extra taxes or customs . I already had my plug ready for the USB. The most unique feature are the lights on the board that evaluate the strength of your moves for each piece. Great back up team support for any questions. So far I have only been playing the board's AI opponents , but will move to Chess.com eventually . But as a teaching tool it is perfect for my young nieces. I can't recommend this Chess board enough. With updates and info from the team, things can only get better . Thank you for a wonderful experience !
