Bought this magazine used at my field for $15. Use this in my upgraded combat machine that shoots at 15-18 rps. Feeds perfectly, this mag is known to feed in 45+ rps setups. Comparing this to the cheapest aeg high cap, the dboys 300 mag, this is way better. This holds more rounds and is not painted. The dboys is a good mag too but the build quality is lower. The metal is gray so it won't scratch to reveal crappy pot metal that other mags are made of.
-if winded until two clicks are heard, it will feed the whole magazine(usually you will need to wind it for about a minute)
-very good construction
-real steel mag length
-pricey if bought online( use coupons)
-mine has a dent in it caused by the last owner being hit, this would happen to any metal mag shot from up close
