My wife and daughter both have Saber Red pepper spray on their keychains, I keep a larger Saber Red Gel at the front door and carry it when we walk the dog.
I prefer to have them carry the “liquid” pump style of pepper spray/mace on their keychains because the liquid will splash, mist and not require the same level of accuracy as the gel does, chances are they’ll be under loads of distress if they ever need to deploy it and I’m sure their fine motor skills will be lacking and so will their aim, I’ve also found that the “pump” style canisters are less prone to accidentally discharging while their keys flop around in their purse since they require the “trigger” to be rotated and then pressed, the ones with the compressed propellant normally have a flimsy spring loaded safety that tend to normally break being on the keys.
Although for around the house or when walking I prefer the larger gel style canisters that use the compressed propellant since they have a belt clip and don’t get abused as bad.
I’ve personally been sprayed with Saber, Fox Labs and a brand that LE carried when I worked in a jail, I couldn’t tell much of a difference while on the receiving end and they all seemed to suck equally as much, while not exactly scientific, all of them had me second guessing my life choices haha, I haven’t been sprayed with a gel pepper spray but I’ve read that even though this type lacks the “splash” the gel is far less affected by the wind and chances are we will be more likely to need it to fend off an aggressive dog running loose or to a lesssr degree a beatnik running amuck.
