Nothing new, these fake product have been known at the market circulation for maybe > 10 years, wonder where you've been all this time ?
Well I am not a huge fun of Sanwa, mostly because their products was always at a higher value than others.
But I got there to examine their digital DMM model of 50,000 / 500,000 counts,
and found also their: Customers beware warning.
The point is that I do understand their pain , yes it is called as pain to watch cheap copies of your products to sell worldwide,
and to strangle your own market share, especially those days that things does not go that good for any one.
