I like the powder dropper; the lube syringe is a neat idea. However..you can get syringes with curved tips at medical supply houses or feed stores to deliver crisco or whatever goop you want to squirt in there.
I don't know what's special about their capper. Like a lot of folks here, I can't get #10 caps locally, so I make do with #11 caps and squeeze them before I snug them on the pistol, I can't use a capper unless I get a set of #11 nipples..
