What a downright shame and nightmare this must be for Petzl and its customers. I hope that examples in customer service like the one in this blog's comments show your customers that you are serious about helping them understand the origins of their product. When one is considering climbing gear, safety has to be the number one factor. Knowing that something comes directly from Petzl and not some overseas counterfeit outfit comes with a high degree of assurance. Good luck to Petzl in identifying their products as well as hopefully putting an end to those who are passing off your products as their own.
