Co2 inflator (1)

Anyone have any good experiences with control drive co2 inflators? Was looking at the Lezyne Control Drive, but read a couple reviews that you couldn’t close the valve all the way to make the co2 completely stop. Just looking for first hand experience, or if folks really feel you need something that can control the co2 vs the standard…

Portland Design Works “Shiny Object”. Great CO2 inflator head. Control knob works as advertised.
While you can close the valve all the way so that the CO2 stops, bear in mind that the control knob won’t lock.
