Got my Sigg bottle bought in 2012. Did she is's only filled with water (for better cleaning). Had she doing in the service and sports. I was a real fan of these send water bottle, I also in the youth already so had a yes! Now I realized when cleaning the bottle that the internal coating somehow feels rough and laminar. After I slipped several times with his finger on the coating, a transparent scraps of the coating peeled off. She smells now also strange to chemistry. So something I will have neither in my drink still take me! I realize that aluminum must be coated, otherwise traces of aluminum may end up in the drink, which is also not supposed to be healthy. Must probably look around me unfortunately to another manufacturer and possibly another Flaschenmateriel (stainless steel or BPA-free plastic).
