I was a little hesitant at first because of some bad reviews on the net. I went ahead and tried a few mags to see and I've found that the first pellet that you insert thru the clear front plexi isn't positionned as deep as the 6 other ones and this can lead to insertion problems when cycling the movement so now after I've inserted all 7 in the mag I use tweezers to push the first pellet at the same depth as the 6 others. Since having done that I have bought more mags for a total of 7 and they all work flawlessly, so now I can shoot 49 shots without reloading . These mags are a great invention

They work great! Adds to the fun factor, for sure eh!
