Adept gun for years, doubt is installed. Indeed the last cartridges, 510 or 511, the rating of 5 stars and lost as to lose the triple "A" of France in économie.Pour the same use as before, especially bureantique, I do not even speak pictures is a little cat, the cartridges are empty ua délirente a pace to believe that a full half-done. Always the lowest price but they need to buy more often !!!!!!!
