Judging from the address on that site (Embassy Pool Co, 315 N Sebastian Street, West Helen, AR 72390), Embassy Pools is an Internet only OR low-end brand of Hoffinger Industries, which is the Doughboy parent company.

The fact that Hoffinger appears to own the company would suggest that the warranty actually means something, and this page,http://www.embassypools.com/, indicates that the pools are US made, which is good.
