Hi, may I suggest some ideas that would be not that difficult / expensive to implement however they stop effectively the counterfeits? - Put a unique, non-continual numbering serial number INSIDE the packing of the product in a way that it is not possible until the product is purchased and the packing is obviously opened. Then this number could be entered on Petzl' homepage and verified whether it is genuine or not. - Put some hard-to-reproduce holographic watermark on the product / packing of the product. Regards, Mr. T.J.
