The bottle on the AirZound will split, but you can retrofit a 1 or 2 liter plastic soda bottle.
A good friend of mine has had the same Air Zound horn on his recumbent for 3 years now. The bottle is original.
Thank you for the info though! If mine does split at least I know that a soda bottle will work.
