I know it sounds like a stupid complaint, but a 500ml water bottle would not hold up-straight in the front side door holder.
I understand, usually the large the holder is, the better.
but any Idea of a 'strap' that would help smaller bottles still stay up in staid of falling horizontally, concerned about the possible spill ?
I understand I could get a larger bottle, or use the cup holders, but not convenient while driving
