Hello, new to the forum but need some advice. We are looking at buying the M500 and after doing some research I read some posts that said that the warranty is not valid if purchased online. I have been pricing this model out and it's as high as $1700. Poolpartz has it for $1199. When I messaged the company they said that for a new model it will come from the manufacture with a valid warranty. My husband is skeptical. Any experience with the seller? Any advice? We are new pool owners and need some help.
