Now this magazine has been a great one for the first 6 months that i had it. I tend to treat my guns very well and after about 6 months it started leaking from the screw on the bottom where you insert the co2 cartridges. Now I did use this gun just about every weekend so for those people that dont play quite as much you will probably go longer before you need to replace it. All in all it was good while it lasted and im guessing that for the people that get out and play airsoft every other week or less often than that it will easily last at least a year or year and a half before you start seeing any stripping on the screw. Even the best gas mags under the best care will need replacing if they use a screw system like this one because after you have unscrewed and screwed in a screw 1000+ times it starts to wear on the threads but for me It was definitely worth it.
Much better than propane for cold weather
I like the sound better but that is really just my opinion
like any other screw will eventually strip but really think about how much you will actually be changing the co2 cartage because this mag will last you a while
slower to reload than propane (but you can reload a few bbs without worrying about changing the co2 cartage)
