Don't buy a Cal-Spa hot tub

We bought a Cal-Spa hot tub, including the service agreement. Within 2 months the heater needed to be replaced. A motor was replaced and the whirlpool knob was replaced. Three years later, the whirlpool knob has never worked. We had to replace the heater a second time. The service people in california would not respond to our local people. During the second repair the hot tub was out of commission for 3 months waiting for parts that were promised within 2 weeks. After many complaints, the california Cal-Spa people stopped returning phone calls or written requests. They simply 'ignored' us and our dissatisfaction. I hope that somebody reads this and NEVER buys Cal-Spa brand so they don't have the troubles we have!!!!
