Things I liked: cost, accuracy don't have much to compare with but can get a good group out of a just purchased winchester m14 dual co2 cartridge repeater (8 shot repeater) BUT see next section
Things I would have changed: quality control is bad. Between 5% and 10% of pellets either had obviously out of round (ie flat on one side) skirt rim, and / or lots of pellet debris inside the skirt. Had to inspect each one and discard the bad ones which grossly slows down loading the repeater magazines. Was afraid to shoot any with the tailings / burrs or other debris as thought might require frequent barrel cleaning. Also MANY SEEMED LOOSE in the magazine and I had frequent jams. As I bought no others, and my other rifle is a 22 cal I can't compare to other manufacturers pellets.
What others should know: you get what you pay for....
