Had my Square Off PRO for a few days now and have played 12 or so games online. There were some initial problems updating the firmware but after trying on a few different devices it managed to install via the iPhone app. My router also needed to be reconfigured to broadcast on 2.4GHz which was easy enough to do.
I've only been using the PRO for online games as I prefer my DGT Centaur for playing the computer. I do have some minor gripes with the PRO (like the annoying sound effects in the app and the board being a bit of a dust magnet) but so far I’ve not encountered any major issues and it is working as intended. I also like that I can run the app on my Macbook. Overall I'm satisfied with my purchase.



Got my Pro this morning - a little hiccup getting the firmware updated, but after that it worked flawlessly in a couple of quick games against the AI. Will have a chance tomorrow to try out the Lichess integration.
