This mag is pretty good for the price. I own about 3 now. As far as high cap mags go, this one is good for the price. you need to shake it a couple times or it wont feed right but thats no problem for me. if you want a good mag for a good price this is about the cheapest mag that still manages to deliver good quality.
easy to load
feeds good when used in Echo 1 brand guns
looks great with a black MK16 (thats my personal opinion)
Needs a few shakes when winding to get a solid feed.
Takes a little longer to feed than other high cap mags (this allows a solid feed)
