Question: does the flashlight have a strobe effect?
Document: Solid construction. Two sets of prongs. Loud and effective. My son and I tried it on each other and it will make an attacker think twice. Note...the effect is short lived, meaning use it effectively or run afterwards. Also, the flashlight runs the stungun charge down rapidly so if used as a flashlight for any mid-length of time recharge afterwards. Nothing worse than an uncharged stungun in an emergency.
Very satisfied. Good service. Cute case. I can feel myself safer now. Hope, i will not use it or maybe flashlight only ( nice feature by the way).
Very durable and easy to use. Flashlight very bright and the stun technology works excellent. However, would be nice if it came with a travel or belt hook case.
This gazer is AWESOME. Love the grip and the smoothness of the skin. The flashlight is good quality for so little and the zapper is OFFICIAL! Love love, and I wish somebody would.........ZZZAAAAAAP!
This product is small and powerful. The ac prongs come right out of the handle so no charging cords are needed. i also like the safety feature but i wish the buttons for flashlight and tazer were flipped.
Construction is shoddy, but for a basic flashlight and zapper, it'll do. Stun zapper is loud and scary-sounding. Flashlight was strong, but it just stopped working after a couple months, so I can't recommend buying this product.
I bought this item for my wife she loves the security of the flashlight and being able to defend herself at the same time. Our 30 year old son said that stun guns only gave her some what  protection and wanted her to zap him to prove he was correct.
So far, I 'm very happy with my purchase. Stun gun arrived exactly as described. Very easy to use, perfectly fit in my hand;you don't have to worry about batteries;and very great idea- build-in flashlight.Will recommend this product to my friends!! !
I havn't used this on anyone yet, but hopefully never will. When you hit the tazer button, the loud crackling noise will probably back anyone up away from you -- it is very intimidating. Great flashlight with extreme brightness also. It is a smaller flashlight which I like, you can stick it into your pants pocket just enough; any bigger and it would be too bulky to carry in your pockets.
This flashlight is a little bigger than I was expecting but it works perfectly. I choose it because it is easier to carry on duty than the full sized flashlights provided by the department I work for and because it is rechargeable. The stun gun was an added bonus for me, I would've made this purchase without that feature. Based on the brief recommended check on the stun gun feature it works.
Answer: yes
