We bought an Optima as our first spa after great reviews from a longtime family friend who had their first Sundance for 15 years and just replaced it with an Optima. We live in Northern VA and use it year round. It was a great addition to the family and serves as a family gathering spot, and really helps remove the stress after a tough workday. While I’m sure the electric bill has gone up, it wasn’t noticeable, as our kids and their electronics are probably bigger consumers.
We chose Sundance over other brands due to its high quality reputation and longer warranty then others. This did of course come at a price premium to other brands. That said, we were very surprised how after only 4 months of use, that several of the blue LED lights started failing (odly only blue). It started with the waterfall light bar and then spread to the LEDs around 3 of the air control valves. Our dealer came out and did the repairs under warranty once it warmed up outside, which I might add were not simple repairs, and required cutting/ripping out the foam insulation. The insulation was replaced following repairs, yet I’m certain it is no longer as well insulated as it came from the factory. Then after 10 months of use, the blue LEDs around the remaining air control valves failed. We are now waiting (as of 11/22/15) on repairs, and it might already be too cold outside to complete. Pretty disappointing for such a high end spa.
