What a piece of junk. We purchaced a caldera spa in5 20 2007 and had nothing but problems starting with a burned out pump. 1 year later the shell bubbled and had to be fixed by a third party that did not even come close to the original color! Ibought this because i am disabled because of back surgery gone bad. Now the warranty is almost over the heater stopped working. Our ocal dealer stopped working on the product they sell. The third party wanted 85 dollars just to look at it. What happened to parts and labor. Now that its fixed and out of warranty it is now for sale and will be purchasing a national brand like jaccuzzi. What a waste of 8300 dollars. P.s it was a tahitian.
