Start and Stop times are a litte on the short side. I can still see ver well 30 minutes pos sunset, so I guess I push that one. I also bend the Flo orange rule on the military base I hunt during ML season. I wear it in and wear it out but as soon as I get 20' up a tree it comes off and goes in the pack. I still have quick access to it if I see someone coming. I will pull it out and wave it to get their attention.
