Congrats, I'm glad to hear you got one
The follower really isn't the problem, the mag has a tab on the side so you can move the follow down making it easier to load, if you move it too much the rounds can drop in pointing up or down. It's can be a pain to get them fixed when it happens though.Sounds like a candidate for a "no tilt " follower though.
The main down side to the mags is the cost, they are averaging $50, GSG has them listed for $35 (I think) but they are always sold out. I wish someone would make a mage that works in these, I bet they can be sold for less then $20, I can see about $20-25 for one of these factory mags but $50 is nuts.
