Doesn't push paint down the barrel, just pulls it out.
Wont work well with freak systems, the sharp fluted holes will cut the rubber piece
I love this squeege, i break a ball in the barrel, pull it out and and flip it open, ram it down pull it up and clear shootin from there. I had a problem in the past with a freak because the sharp fluted holes would cut the rubber. I use a proto barrel not and the fluted holes arent sharp so it works fine.
I don't know about these other guys, but you have to use common sense when using it, use a squeege only when u get a break, not just to test it out cause then it will get stuck. i broke one and that was because of the sharp fluted holes on a freak, but other than that i like it.
