First, the latch that holds the spring plunger in place was badly bent on arrival. This is very thin sheet metal and I was able to bend it by hand. Second, some parts are rusty. And thirdly a whole case of clips doesn't fit, I have to remove exactly one clip from the case every time I reload, how ridiculous. I think I'm expecting too much from a well-known brand that has had almost a century to solve these little problems.
