I will here write anything about the battery, the quality is known. A little disturbed me advertising with Bonus Pack 8 + 2, in which I initially assumed that since 8 + 2 batteries, ie 10 pieces in it would. However, the +2 relates only to the battery safe, ie a plastic sleeve for the batteries. If you read the offer exactly can you naturally see, but I have a feeling that will be played in order here, that one looks over it only superficially. I went there anyway so therefore only mean score. With the quality of the battery that has nothing to do.
