I can say that I have been using them for YEARS, and have had zero issues. The argument about them getting exposed has no merit for me. They are sealed for a reason. So I am suppose to trust my life on Cotton balls setting in a shed for 25 years... are you F-ing kidding me. I care enough about my life to check my gear regularly. If I ever found a packet with a hole I would replace it (I have not yet, but I would)
I do this stuff, its what I do, not just talk about it on the internet. I hunt, I scout, I'm out in the bush alone A Lot. If I scream NO ONE will hear it, yes, you can say I bet my A$$ on my gear.
