In order to provide a guaranteed customer service to our customers, we have introduced an authentication system aimed at insuring that you, the customer, get maximum customer satisfaction from our products. End users can check the authenticity of the purchased unit by scratching off the bottom part of the seal to reveal the 16 digit authentication number. Go to our authentication webpage, type in the 16 digit numerical number and press enter. A message will appear to confirm whether your purchased product is genuine or not.
