So far it has been an extremely reliable product that was fun to get some scripts running on. I use a raspberry pie with a cron job to update the board with the weather and my daily schedule. Board actually looks extremely repairable for each individual character, and have has no issues with reliability in ~6mo.
API currently is through a rest interface which they have promised to keep free despite charging for plugins shared through their a subscription model. They had promised a native/local API but I have not heard anything from that.
Overall would recommend but it falls in the tech art category for sure.
