The duration is not bad, there are a lot of different shots even if one does not use half but I guess you get what all different use, I take one star because the heads do not take not in special slots, if the box is returned, you went to put everything back in its place, the magnets in the bottom of the slots were the idea of the century for storage, suddenly I had these in the benner left loose, fortunately there are only 45 relatively recognizable heads
