There were issues but quickly corrected.
Original order came really bad - bad packaging and battery shipped was dead. Seems like somebody made mistake and wrong product was sent. So, while things like that should not happen, after contacting customer support, issue was quickly and professionally resolved - new and working battery was sent within few days. I give 4 stars because "things can happen" and I hope vendor corrects this though resolution was prompt so they deserve the credit. I would use this service again.
