False advertising - CompMag AR-15 5.56x45 10-Round Compliant Locked Magazine

So a little over a week ago i decided to order this item and just the other day I went to use it and my bullets were get jammed and it was not feeding anything so I decided to take a look and the whole top half of the magazine was cracked and scratched so for $70 this mag is so not worth messing up a gun. It has to be the worst mag I’ve ordered. And for the screwing to expand the mag that in fact does not work. Id keep my money and walk away before I buy another one!!
