another review of the BookArmor cases
One reviewer noted a strong chemical odor from his case. I had the same problem with mine from Amazon.com. OmniScience quickly replaced it. I was told by the manufacturer that one of their boxes shipped from a supplier in China had storage problems and the transfer container got very hot -- causing odor issues.
My replacement BookArmor cover has a very very mild lemon-like aroma that gets weaker every day.
