I have one of these. I've only used it so far a week backpacking trip into the Grand Canyon. This bag plus an odor proof liner worked great! I used a larger carabiner and hung if from a low branch. No rodent issues at all. Other people in my party used the heavy, metal mesh rat sacks. One determine rodent was able to get it's teeth in between the mesh links and chew up plastic baggies. It couldn't get the food but who wanted nuts with rat slobber one them?!?!
ZionHikes1I'd assume the bear bag was hung and the other bags not. Typically, something like a UrSack is not hung from a tree branch, it's left on the ground since there is less need to play "keep-away" from a bear.
