Love the idea of this
Love the idea of this collapsable water bottle. I followed the "first use instructions" and boiled for 15 minutes, but now part of my bottle has a different look/texture on the exterior of the bottle as if boiling it took of some of the silicone's coating (it looks like there's a powder coating on top but feels like nothing). Understand that it's important to sanitize products before consumption, but wish there was a warning about tainting the exterior coating when sanitizing.
