Counterfeit Pokemon GO Plus devices hitting the Japanese market

Looks like Nintendo and Pokemon Co. have an issue on their hands. The market is being flooded by counterfeit Pokemon GO Plus units. The thing is, the fakes are ridiculously close to the real deal, making it super hard for customers to spot the difference. The only real differences are the lack of a Nintendo logo, slightly different coloring on packaging, and a lesser quality strap. Nintendo is well aware of the issue, and while they haven't stated what they plan to do to squash it, it's very clear they have a plan set.
