Query: Could not view product because significance of "region 2" not indicated in the product description.

Product showed region 2 without explaining that it was not compatible in the US market. A total waste of time and postage even with a refund of the purchase price. The significance of the region 2 information was missing and only revealed by a subsequent off-site investigation. Even a refund of all expenses is unlikely to overcome this bad impression.
