How do I check genuine Butterfly products?

[amitmnagarwal]

Is there a way to validate genuine BTY products using serial number of bty blades, rubbers?

If you're in china or you buy china-specific products (eg. golden viscaria) you can check on http://butterfly-china.com/

Otherwise, you would need an insider at butterfly to check your serial number. people have reported emailing them before with the number to no avail
