I used it the once and to be fair it is not as amazing as the description on the box makes out, but it was ok and it did the job; I just rarely ever need to speed load multiple magazines, so never put it in my range bag.
My advice is to not overload it, just dump 30 or so into the hopper when you want to load a 25 round Magazine.
I used this for magazines on the Smith and Wesson M&P 15/22.
Can pick up in person or I will post for extra.
If posting then PayPal is preferred as it protects both parties.
