Hello,
As this is an extremely serious issue be sure that we are actively preparing more informations concerning the identification of counterfeits. We will of course inform all our customers, retailers and distributors. In the meanwhile check with the distributor of your country that you have purchased products through an official dealer. http://www.petzl.com/en/page/petzl-distributors-world-1
Thank you for your interest
