Kluson MK6LN Tuners

I wonder why these quiet small machine heads generally gets so fine reviews.
Maybe they have been produced some other place earlier?
The package holds no information of production country...
First thing I discovered was that the six enclosed small screws is a really cheap quality.
Made of old time "China quality" metal.
Next time I think I will buy either more expensive machined heads by another brand or some cheaper made in China, which proberly will be a least same quality.
