Thank you to those who gave the tip to buy on Amazon US sales management but Amazon France had read these comments because the US site accepts over deliver HQ in France, while it remains possible for others accessories. This allowed me to still learn more about the subject of discord. Even for $ 40, US buyers do not find it good so I understand that for 150 poor French buyers are more than disappointed. I will pass on this purchase, there is ample opportunity to gifts. It remains to wonder about the website trade policy. As marketing manager, I am puzzled. A good shot and a good margin on a product is worth it really worth losing customers as I read in the comments and lose a good brand?
