Made by a company called DIP in Romania go to this link:
They are a clone of a Ditting Grinder (KR804):
go to this link:
These are deli or shop grinders - and are used by these stores to grind the customers coffee to any degree of fineness or coarseness they desire (from espresso to percolator). These are for their customers who do not have their own grinders at home.
The DIPs are OK but if you had the cash you would go for the Ditting everytime.
If you are thinking about it to grind your espresso coffee at home I would say you are going in for an extreme case of overkill.
