When these were first made they had some issues but these are now corrected. They are a lot of fun and about as close to a real DP that most of us will ever see. Mine is a bit picky in regards to ammo but that is not a shock. It likes some ammo and hates others but it is not so picky that only one or two types work. For the most part my DP eats the ammo fed to it but for some reason the Polish (and a couple of others) do not agree with it.
