We are enjoying the spa, almost daily.  A few quirks, however.  Resetting the thermostat doesn't necessarily get you the temperature you want, especially if you are trying to lower it.  It seems to have a mind of its own.  The pretty flashing LED light board lasted about a week, then stopped flasing.  Installation of the ozonater required a company tech, because the neoprene line was buried too deeply in the foam insulation for me to get it out without disturbing the other lines running next to it. We did get very good customer service on the ozonater installation, however.
