Pew pew pewThe 1st 3 times I have ordered this Amazon has sent non biodegradable ones. The product itself is good Amazon just needs to step up their customer service!I've had these for over a year and use them to discourage the destructive "fuzzy-tailed rats" that pillage our bird feeders and chew them to pieces. It doesn't do any permanent damage to them but they sure do hate getting hit which makes them run off. I've found several of these that are over a year old and don't seem to have "become one" with nature yet. With all the plastic pollution that we hear about in the news I really was hoping this would be a viable solution to straight plastic airsoft pellets. Maybe they just need a little more time to degrade... Overall fairly accurate - have it on a scoped single shot bolt action sniper rifle and it is accurate enough to hit the gray coated scoundrels at 40 feet away...every time. Further than 50 feet and the accuracy drops off to about 1/2 accuracy - so effective enough to keep them out of the back yard.Nice balls. About the only thing is I would like different colors.Four stars for value because they're a little cheaper at the store (but it was worth not having to go to get them). Other than that, they're great. Very accurate, consistent and won't be scattered all over the ground forever.Love this! Worth the money we have already bought 2 tubes!This is my second purchase of these airsoft pellets, twice the order was for biodegradable pellets and twice the pellets delivered were not the biodegradable ones as pictured and described.Good quality.
