James L. Bowen rated us:
: (5/5)
Product:: unknown battery (1100 mAh 3.7 V, Black)
General:: What can one say. Your service was spot on from notice of order placed to delivery of product. Quite impressive for an order originating in one country (USA) and placed in another (England)and shipped from another (Hong Kong)!
About the product:: Product (Cowon X5 battery replacement) made the Cowon perk backup from 2-3 hrs paly time to the orginal 12 hours plus. Thanks y'all1 Larry
