Has anyone used lipstick shaped stun guns?

I live in a big city and often come home late at night. I want to buy something for self-defense, but to make it look inconspicuous and stylish. I came across lipstick shaped stun guns. They seem like the perfect option, but I've never used such devices before. Does anyone have experience using such stun guns? What models would you recommend and what to pay attention to when choosing one?

I have a stun gun lipstick, and I can say that it is a really convenient and effective tool for self-defense. I also like that it looks like a regular lipstick, so it's easy to carry in your purse without attracting too much attention when I was choosing my stun gun, I paid attention to such features as voltage, built-in flashlight and ease of use.
