Yeah, unfortunately their quality's not dependable. The example caps are notably more consistent. You'd think that since they were doing something so specialized, even esoteric, they'd have higher standards.
A friend of mine ordered an Ultra Classic KB from them earlier this year that looked so good I ordered one too. When it arrived, I was disappointed to find that all of the text legends were indistinct and over-bold. It really looked amateurish; I never saw work like that on any KB. So regretfully, I returned it, and found and cleaned up a mid-'90s Lexmark instead, which looks vastly better.
All told, your caps look pretty good to me. The symbols are clear enough; there's just a bit of variation in the placement. If you're not demanding perfection (which is unrealistic anyway, with these people), they're fine IMHO.
