Bought this so I could walk on the parkway alone without feeling like a sitting duck. I really wanted a taser, but Big 5 doesn't sell those for some reason. We were joking that I could get an AK47-style paintball gun and it would have better results. It was just too bulky to carry though. Gotta have my arms free to do the 'mall walker' stride.
I asked my cop friend to tell me what the stats are for women being hassled in that area, and I didn't hear back from him, so I took that as bad news. I personally think that being overweight (read: chubby or fat) will deter most perps, but there are probably a few bad guys out there that wouldn't care about that.
But seriously...I do feel safer. I'm glad to have it.
