I am looking at buying a cell phone style stun gun and it appears there are two kinds: one with batteries ($24.99 - http://www.thekrazykooljoint.com/Cell-Phone-Rechargeable-Stun-Gun-25-Million-Volts-cellphonesg.htm;jsessionid=08FF6BE257840DA914B27076AD1738DA.qscstrfrnt05)
and one type that is powered by two lithium batteries ($79.99 - http://www.beststungun.com/firestorm-cell-phone-stun-gun.html). I am wondering what the advantages/disadvantages of rechargeable vs. battery are other than long run cost such as how long does a burst last from either one last before having to be recharged/replaced, etc. Do you get multiple blasts before you need to attend to power, etc.?
Does anyone have any experience with devices at all?
