I got these because of all the "Good" reviews they had, but I have had problems with these mags from the start! They jam, mis feed, and brake. From the start, two of them jammed, and one the follower broke (the other fixed its self, for a short bit). All of them have jammed when loading, or firing them. Ill be in the middle of a fire fight, my gun will stop shooting them, I slap the bottom of the mag and hear the spring catch again and then I can start shooting again. I never know if they are going to work, or fall apart in my hands. Had one split right in half after only loading 20bb's.
I got two extras with the 8 pack, so out of the 10 I had, only 5 of them are still working (and its really hard to even use the word "Working" to describe them)
Jam when shooting, or loading
Never feeds the last few bb's, so you never really know if its empty, or jammed again
