Update: while the batteries and replacements were not at all up to par, the sellers service was great. After the replacement batteries were still not effective they issued a full refund. The charger is decent and I like the gauge showing how charged they are. The batteries themselves are horrible. They claim to have higher capacity than the original Sony, but they are just as bad as the old third party batteries they were supposed to replace (they at least worked well for a couple years). Pulled one out of my bag today and it was down to 10% charge without being used. The company sent me two replacement batteries but they are just as bad as the original.
