Just to be a pedantic PITA (I know, me?!), but that wouldn't matter here as the SOGA would override any manufacturer warranty at this point. Really, they're pretty much useless as your contract is with the person who sold it to you, not who made it. If it's non-compatible, then you are due a refund.
But yes, I would only ever buy parts from a reputable dealer in this country: You only get bitten once to learn from that mistake.
