Easily change cartridge, but clip needs new design
I love how it's one piece. It holds the pump very nicely, and you do not have to take it out of the case to change the cartridge. The biggest down fall is the clip. Just from sitting down the pressure is enough to slide the case out of my pants or belt. I like the old style clip better. The new one needs a hook like the old style that one help the pump in place.
