These are ratings of our store left by verified buyers on our eBay storefront — same company, same warehouse, same people packing the box. They are feedback on the purchase rather than reviews of this particular item. eBay’s one-click “delivered on time” feedback counts toward the rating but is not quoted here, because nobody wrote it.
