Does anybody has any experience with Wasabi batteries for E-M1? I've always read mixed reviews about them. Some people swear that they are as good (if not better) as the original battery while others say that they do not last long enough. Also, from what could gather from some of the reading online, it seems like Olympus batteries are chipped so the original charger will not charge these batteries but original can be charged in the wasabi charger? Update: I'm going to go ahead and order Progo battery as they seem to be the only one that charge in OEM charger.
