Question: Seriously, will this stop a charging dog, a PB, Rottie, Dobermann or even a Lab?
Document: Compact and appears easy to use. Quick delivery and hopefully will stop any dog or dawg attacks. Should work fine with the bike.
A charging dog can cover that distance in a split second. I'm looking for one with more range.
This stuff simply wont deter anyone who really wants to hurt you. Maybe if you got it RIGHT in their eyes it would sting pretty good. Topically (on the skin) it barely produces a 'warm' feeling.Also, the unit only sprays the nasty brown juice about 8 ft and not very strong stream. My grandpa's misty, stop and go pee would travel farther than this.Dont buy it. Seriously.
I run with this all the time. I don't even realize its there. I've had to use it on an aggressive loose dog once and it did the trick. The dog backed off, but clearly wasn't going to suffer any permanent problems.
I don't sympathize with dog owners who alloy their viscous dogs to chase and bite cyclists who have every right to use the roads without being assaulted. So therefore I don't feel at all bad for spraying their dogs, even though they're the ones who really deserve it for letting their biting dogs loose to hurt people.
The bottle stays snug and has never fallen out. The velcro seems to hold well, even through my sweat.What is interesting is, no animal has even come close to me since I bought it. On the one run I forgot to take it with me, I was chased by a dog, but every run I have it, nothing. It is as like they know it will not end well for them.Out of curiosity, I did spray a stream of it to test it.
Turns put the owner had received a warning about not controlling this dog after it bit someone else and yet it had slipped outside. Unfortunately, these things happen.That was all it took for me to realize that I wanted some protection with me at all times. Also, crime is up in even "safe" neighborhoods in my city. There has been a surge in home invasions lately. And with the holidays approaching,  parking lots at shopping malls can be risky areas, especially at night.
This personal protection sprayer is well made and the carrying pouch is handy. I did have occasion to use it once and the sprayer stream went much farther than I expected. I used it to keep a roving dog away from my dog and he promptly left even though the stream did not touch him. The reason I only gave it three stars is that shortly after I used it the canister fell out of the pouch and was lost. It was a bit expensive for such a short term use.
Same day I received it, I went for a run and it fell out of the holster, I didn't even realize it until my run was complete.
Product did not spray correctly. Liquid came out brown even after shaking product. Useless! Want refund. Waste of money and time ordering.
