There really is not much to say to the batteries themselves: They come in original packaging and therefore can be individually taken from this. The longevity, and thus the main argument of a battery is also given here, thus I find the price of about 1.50 per battery entirely appropriate.
Certainly you can get such batteries even cheaper in various 1-Euro-shops, but one has with these usually then not really long fun. Of all the dead batteries, which you then laying around at home and somehow has to dispose of, even to mention.
