The board is great! It is responsive, easy to set up and intuitive to use. The pieces are of high quality, and I like the fact an extra queen is provided. The board senses moves impeccably and stand-alone, enough variety is offered with the onboard difficulty levels. The app (I have the iOS version), although showing great potential and already improving quite a bit since my time of ownership (autumn 2022) did crash on me a couple of times. The lichess integration seems to work fine, chess.com integration would make it 5 stars. I hope the company persists its rhythm of pushing out updates and improving functionality
