I bought the so called 5* battery. It seems good but it degrades quickly after few charges. People review mostly in the first week (battery works and seems good), but the battery will lose original capacity in few weeks. If you read carefully you will find these reviews. In my case I am down 10% capacity after 11 cycles. PS: Battery is a sensitive item and cannot be shipped by plane. This explains the cross border problems.
