1 of 5 Won’t feed properly August 2, 2021
Reviewer: Jake H from Oklahoma  
I was extremely excited for these mags but unfortunately I cannot use them. They won’t Re-chamber and seat properly after each shot. I was told by the ETS Instagram page to store my mags loaded and that would solve my problem, which I already did, yet even doing it again it never helped it. Cool mags, cool products, wish it were usable for me.

1 of 5 Purchased 6, all 6 failed April 13, 2021
Reviewer: sw10mm from New Mexico  
I tried to work with ETS, explaining that the magazines wouldn't even insert.  I sent them videos and pictures.  I used a dremel and sandpaper to file it down to make it workable.  In addition, the magazines wouldn't feed the last round.  They sent a stronger spring, and that made it work.  As they are, I cannot recommend strongly enough to choose another option.

1 of 5 Unusable. March 19, 2021
Reviewer: Paul Sherman from Davenport IA  
I had high hopes for these... unfortunately they are absolutely useless. They swell so much they dont fit in the pistol once loaded. I have videos demonstrating this for anyone interested.

3 of 5 Good mags, bad ejection January 25, 2021
Reviewer: Ben from Texas  
The magazines are great. Seam to be durable and hardy. However I'm having an issue with the ejection. With the magazine empty, there's no issues, when loaded they won't eject at all. Nothing gets hung, just feels like the magizine is a tad too thick.

3 of 5 Needs a little work January 23, 2021
Reviewer: Sig Fan from NH  
Bought a few of these because the price is right.  Friend he uses them in his Glocks told me they work well.  However, when I went to use them, my slides kept locking back with 1 round left.  Tried multiple magazines, both 15 round and 17 round mags, tried them in both my P320C and my AXG full size frame.   Same results for 6 out of the 7 magazines I tried.  Upon further examination, I discovered that the little tab on the follower is just a little too tall.  It sticks out just above the edge of the magazine when there is one round left and pushes the slide catch up.  I was able to use a razor blade to cut off a tiny bit of this tab and now they work fine.  If they could just fix this tiny issue, I think they would be great.
