Looks interesting. Anyone have experience with these?

I can testify that this is a great item.  Perhaps not for in the field, but certainly for loading mags before going into the field, and having in your camp.  Faster than an Uplula, easier than stripper clips.  Definitely NOT small or light, though...  To me, at least, a well worthwhile investment...  Works great, and nothing to break or wear-out...

I've got an ACEM gen 4, maybe not this model though. Much faster than a Lula loader. The method is similar to loading a rifle that uses stripper clips. I suppose putting your ammo on stripper clips is an alternative, but not something I'm prepared to invest time doing. These are really "plates" as in 6" x 20" or so. They fit in a backpack but probably a little awkward to use in the field (any mag loader is awkward to use in a field though...)

Anyway, there are the best loader I've found. Lula's are good at being small and helping you load a mag, but these loaders are at least 4x faster than a Lula.

I can testify this loader is amazing. As another has said, it isn't light or small by any means but loads any magazine that you or your friends should have at the range except for pistols of course but again great loader. Great design and great company!

Any update on this? Eager to purchase one soon.

I have this unit, use it, and highly recommend it.  It works, and works well.  Worth every cent.
