Ultraflate PRO with cylinder
PROSThis inflator has a cylinder that you can put a CO2 cartridge in and then tighten the cylinder to puncture the cartridge. This allows for the use of threadless cartridges. Although the cylinder is designed for use with only 16 gram cartridges you can put paper in the bottom of the cylinder to take up excess space. This will allow you to use even cheaper 12 gram threadless cartridges. You can also ditch the cylinder and thread a cartridge onto the inflator head.
