The roll out board would not lay flat, and after 7 days of leaving it lay out on a flat surface it is still not flat. At least; the pieces are not moving off the squares by themselves any more. I have only finished about 40% of the games I have attempted with the AI because LEDs start flashing , the board locks up and the game refuses to reset. I have requested to Square Off to return the product or replace it by email as I was instructed, and I have heard back from them after 2 days that my request has been elevated and I will get another response in 2 more days.

As designed the SquareOff Pro is a great, innovative product. Here are my pros and cons.
PROS
- auto-recording of OTB games
- playing OTB against online opponents at slower time controls, e.g. 10+10
- compact-ish (in its product box)
- useful options to play against app engine
- ChessHouse is a great supplier (trying to buy direct from Square Off for international delivery was not a good experience)
CONS
- the in-board firmware and app (especially) is very buggy, but this should be completely fixable over time if Square Off make the effort. The bugginess only screws up games < 5% of the time (currently).
- working around the bugginess (e.g. recovery from error states) takes patience and a little adjustment (e.g. in how one moves the pieces) from the board owner
- the Square Off community is too small to be useful for online play
- the Lichess app integration (I haven't tried chess.com yet) is still poor and only just on the right side of usable (bugs = big rating losses because the ELO matching doesn't seem to work)
- playing against the AI (engine) is very useful, but Stockfish's skill levels (to make the engine beatable) is clunky (obviously dumb moves to lower it's ELO) and not very human. But learning to accurately win against a handicapped engine is clearly useful and playing out endgame positions is great.
- the price is a bit eye-watering, especially for international customers (to the UK cost +£50 for fedex and +£60 for customs).

So, bottom line, the SquareOff Pro is a very cool chess tech with definite benefits (for learning and playing chess). The hardware is fantastic. The software is early days and SquareOff need to be careful it doesn't devalue the hardware. The price/value is up to the buyer but I'm happy so far, hence 4*. When I worry I worry about the long-term reliability and reparablity of the sensor wiring in the foldable board element (already received/replaced one defective board).

I purchased the Square Off Pro in order to get better at over the board play. I find playing on a screen does not replicate the perspective of looking at a physical board. I have used it to play others on Lichess and Chess.com and it works well for those venues. I have not tried playing on the Square Off or Chess Moves forums. One enhancement I would like to see on the Square Off app is more choices for time controls (and/or ability to create a custom time control). Currently there is no option for a 30 minute game with increment (choices are 30 min, 60 min or 45'+45"). Hopefully too someday there might be an option to purchase wooden pieces that work for this board. Overall I am really enjoying this board.

I have had the Square Off Pro for a month now and have enjoyed using it. The board looks good and although flimsy soon flattens out. The pieces are attractive but a bit on the light side. Using the app connection is quick using Bluetooth. Once connected you get the choice of Chess.com, Lichess, Square Off, and Chess Moves (never heard of this one). Of these I find Chess.com and Lichess the best. Have not tried AI so cannot comment.
The only downside is the battery. Square Off claim 12 hours of use but I only get 5 hours of play before recharge.
Overall I give it 4 stars. Compared to more expensive computers it is good value. (Sort out the battery for 5 stars!)

I bought the Square Off Pro mostly to practice endgames against the AI (without having to stare at a screen all the time). So far it has worked very well for me, you can set up the pieces for different game situations and play against AI. I think there is a lot that the app could improve on such as the interface, getting rid of the coins/points system, and making it easier to save a position to play it many times without having to copy/paste the FEN every time. You have to be careful about how you move the pieces because if you make a different move from what the board indicates the game freezes and you cannot keep playing, but if you are careful you can even promote pawns without a problem.
