Question: Can you replace the rechargeable  batteries after a year that's all they seem to last at the most.
Document: Mediocre flashlight. This unit comes with a tiny little short charging cord, and it arcs the contacts when you plug the cord into it. I recommend connecting cord to flashlight, then plugging into a switched power source that is turned off, then and only then turning on the switch. The battery is completely non-standard and difficult to remove/replace, and it does not hold charge very well. Do not test this if you need to use it, you are only going to get one chance.
very well made, light in weight, bright light, as good as the high cost one I lost (which was only 5m volts) the reason I gave it a four star  I was telling my niece how I lost the first one, the cheap belt holder broke, brand new out of the box (never used) I pulled on the cheap belt holder with my index finger to show her and it broke like it was a rag.
this is the second stun gun i purchased and I returned the first one, from another company, although I read that Streetwise, as long as it's been around, puts out other brand name products of the same type, so in other words, it competes with itself. The products are inferior and have no quality control.I charged it as per the instructions and after 5 hours, it was still totally dead. But the flashlight worked. Just what I need, another flashlight!
the item is well constructed and it is well disguised to the persons that are doing wrong, like aggravated robbery,  if i would have had one i could have retained the items i was selling.
make an excellent defense option while serving usefully as a flshlight,which most folks carry in theyr car/ emergency kit anyway-great idea !
all you need to do is fire this stun gun off, to warn off aggressors off. its scary just to use, wouldn't like to get zapped by it! !
Works great, the only thing I hate about it, is trying to feel for the on swtch at night.it needs more of a gritt
Useful, easy to carry, incognito are the word I use for this great flash light. No one knows it's a stun gun, they just see a flashlight and move on. The light is strong/bright. It's light weight to carry. I take it when I walk my dog and again no one looks twice at it. Hopefully, no one will every find out what else it can do.
Thia works great on the cats. They come up thinking you'll pet or feed them then you Zap them. LOL It is great!
The stun button is very sensitive and is directly opposite the on/off switch. If you are not careful where you place your hands or fingers on the handle and accidentally push the switch to the stun function you may surprise yourself. Just a word of caution. It really is a convenient device. No one suspects it's anything more than a flashlight. I'm glad I purchased this.
Answer: yes
