Zac Efron did a great job in 17 Again; he pretty much carried that movie all by himself

Although Vanessa is smart in carrying a Taser for self defense, she also needs a good pepper spray such as from Fox Labs. Her first use should be the pepper spray and THEN the Taser. With the Taser you get one shot per cartridge loaded. If she misses, and under stress and duress she probably will, she then has nothing to protect her. Yes the Taser can also be used as a hend-held stun device, but you are now talking about very close proximity and a crazed attacker may take it away. Why let the creep get that close to you? Blast him/her at about 12-15 feet with pepper spray (aim for the face), and continue to spray even if it’s obvious you hit your mark. With a good pepper spray you just need to spray in the direction of the perp to get initial results, and with a fogger spray nozzle (an option) the pepper sprays like a fire extinguisher.

At this point you may not even use the Taser, but it’s still available if you need it.

One nice thing about the Taser though, is that if she does use it and then calls the police to the scene and files a report, TASER International will subsequently replace her Taser for free. Not a bad warranty.
