Query: Concerned about the Warranty

I am interested in purchasing the FHI flat iron again (after 4 yrs). However, I discovered FHI does not warrant the product if sold by an unauthorized seller (Amazon). Another reviewer is correct about the warranty information. An Amazon customer representative (Maira) said that Amazon will replace the iron or refund my money with a year. I intent the purchase this flat iron again. Let's hope it last more than 4 years this time.
