Has anyone seen or tried these? I was looking at windowed PMAGs or EMAGs and someone suggested them to me.

I have never seen them in action and was really in the market to buy a lot of 10 or so and don't want to spend that much and be stuck with that many if they aren't worth it. I suppose I could always buy one and try it, but I figured I would ask around first.
