Vendor great; batteries, terrible
on February 21, 2012
Both my OEM Sony battery and the two Chinese knock-off batteries reported 240+ minutes of life after they were charged. However, the second Chinese battery couldn't hold a charge. Battery life plummeted to 17 minutes the following day. Butterfly quickly replaced it. However, the replacement battery wasn't recognized as "compatible" by the camera. Butterfly quickly replaced it also. Moral of the story -- this is a great price and a quality vendor, but test the batteries as soon as you receive them to be sure that they work.
Further review: Six months later, the Butterfly batteries no longer work. The OEM battery does.
