More Difficult than it Should Be
I like the way the device operates, but it's EXTEREMELY difficult to change the CO2 charger. The screw-in plug doesn't have a good way to hold, which means it's cumbersome to remove and cumbersome to replace. In fact, when I tried replacing a cartridge I ended up wasting the cartridge because the screw cover was loose. My thumb was sore with all the work. So this device gives a false sense of security because reloading in a pinch becomes dangerous
