Counterfeiting and Piracy

Last month I stumbled upon some Asian copies of our product. At first I was concerned about the impact they would have on our sales. I then realized there was much more at stake. Asian copies of our product will have a direct effect on our customers. We cannot provide any product guarantees and more importantly, material certification for regulatory compliance. Purchasing from authorized distributors will minimize your exposure to counterfeit products.
