Counter Assault is a pretty good brand. That's what we were issued.
BTW: We had an "Unauthorized" visitor enter our office one day through an unlocked back door. One of my staff called the Sheriff's (We didn't have any LEOs there that day). Sheriffs picked him up outside. Turned out he was a felon with a warrant and was carrying a large knife. No damage but several of the girls would come in and out of the office on weekends (We all did depending on our workload==we didn't get paid overtime, as a rule, even for 14-17 hour days when traveling). Anyway, I suggested (on the QT) that I train and certify them with bear spray. Then they could check it out and keep it in their office! OF COURSE, I NEVER suggested they use it on a human!
