i've been using the wasabis for a while now on different systems. they've been fine. the combo with the small travel charger is worth it just for that charger.
i've noticed many people from Europe mentioning the Patonas. i'm good on batteries for my Fuji, but i do need two more for my BMPCC. if i can get ahold of the Patonas, i'll try those out, next. i can compare them with the other two Wasabis i already have for it.
i tried the EZOs once for my past Nex. ohh.. they sucked. one had charging problems and would significantly hold less charge than the other.
