Received a letter from UDAP Industries because there have been complaints on the bear spray not deploying. I bought mine at Costco but thought I would pass along. Make sure to test your bear spray before you need it.
I don't favor sprays for critter discouraging. Has nothing to do with brand, size, scent, effectiveness, or otherwise. I favor a minimum of 357 sprays, as many as needed. But that's just me. The concept of sprays is OK for crowd control, but little else I can think of, possibly excepting Pam in pans.
