Warranty has a cost. And believe me it will generaly be in the manufacturers favor. After all they are out to make money. Otherwise the spa industry would be filled with non-profit org's. But is it worth the peice of mind? To some yes... others no. Six to one, half dozen the other. There is nothing wrong with the middle of the road spas. Last year my company of three stores sold 800 Spas/gazebos/Sofpools and 200 of those were a particular 7x7 middle of the road.
