Salty,
That is the chance you take. A macerates your food does not mean you are without food, it means your food is unappealing.
I have used an Ursack TKO since the late 90s. I have never lost food to a bear or an elfin bear during that time...3 or 4 times in the Whitney Zone.
All canisters fail, usually from its owner not doing what is expected of them. They are called bear resistant, not bear proof for a reason.
