I've had one of these for years and it works fantastic. Out of all the gadgets out there for loading/unloading mags, this is the best. It's portable, small, and highly effective. Lets you load AND unload mags, with the unloading being even faster than the loading! No more "scraping" rounds out of the mags, which is tedious and dangerous. Just tilt the mag forward and work the handle as fast as you can and the rounds fall out. Loading is also effortless.... flip the lever forward, drop a round in. Flip the lever backward, drop a round in. The lever compresses the last round loaded down into the mag so you're never fighting the mag's spring tension. Ever. Oh, did I mention that the handle pushes down into the loader itself to make it's stored size even smaller? Fits in your range bag with all the rest of your stuff and you'll hardly notice it's there. Once you have one of these, you'll never go without one again.
