I've carried and used the Sabre brand from CT. Used to carry it on my bino harness when bowhunting when living in BC. Had to use it on a problem black bear at the place I was renting. After several attempts at scaring it off (clapping/yelling/stomping/throwing things at it) at 10 yards, I went back inside, grabbed my can. Gave it another try, ended up taking a step towards me, split second spurt with that spray sent it practically back flipping and tumbling down a ridge.
