Well, the battery is much better than the stock battery that came with the Galaxy Note.  However, the charger is just too complicated.  Need to align the bloody pins with those tiny holes.  Doesn't even do a full charge.

Update:
Vendor showed genuine concern and contacted.me to help. I found a video in YouTube that explained.how to use the variable pin charger.  Works like a charm. Great product. I guess.better.instructions or a video would help.  Upgrading the rating to 5 stars.
