PRO QUALITY  We are so confident about the quality of our products that if you have any product issues, were very happy to either provide a Refund or a Replacement! We recommend only using premium quality threaded CO2 cartridges for 'best performance', such as PRO BIKE TOOLs threaded 16g CO2 cartridges. NOTE: Using low quality CO2 cartridges with potentially poor quality threads and seals can potentially damage the CO2 inflator head and therefore fail when most needed!
