Things I liked: holds pellets well, even inverted. opens wide enough for my large hands to grap a tiny pellet. installs on belt w/o re-lacing. Also fits in the cutout of the Crosman 1399 stock. I have one for my backpacker and another for my Marauder that holds 3 spare magazines (just enough to drain the tank. the pouch closes itself when you bend so you don't dump pellets (most of the time...)
Things I would have changed: i might replace the hook and loop on the pouch closure with some powerful magnets to quiet this up a bit. The rabbits know the sound of my pouch opening.
What others should know: this thing'll hold all the pellets you need for a day of plinking and they're at arms reach.
