We have been using our new spa now for about a month. We had the temp set and chemicals balanced. We noticed that the next use the spa was cooler than what we set the temp at. We are still working on the temp and making sure it stays at our desired temp. I think it needs to be set on AUTO and not the other settings?
The only thing we find NOT user friendly is the display facing the outside of the spa. Most people are in the spa when they are pressing the jets, lights or temp buttons. It would make much more sense of the display were facing inward or have the options to flip inward and outward.
Aside from that we are pleased with the spa and look forward to years of enjoyment!
