This spa is billed as "plug and play. It should be described as "plug and pray."  We have had the spa for 3 months and it has been functioning correctly for less than one month due to manufacturing defects with the control panel (have now had 3 including the original) and the main control board replaced a month ago).  The spa has overheated in 80 degree weather, not responded to the control panel (all three), and yesterday simply stopped functioning.  

We keep the spa on a rear patio under roof, keep it covered when not in use, and had a dedicated electrical circuit installed to ensure proper functioning.  Now we will be forced to deal with its removal and the delivery of a new spa.  Too much aggravation for a simple plug and play appliance.
