I used a company called Smart-Cigs much cheaper than most,
I bought a kit for £30 and it includes ........
2x batteries (which make the body of the cigarette)
1x wall charger and usb attachment,
1x storage box,
4x packets of filter tips (5 to each pack, so 20 tips in total)
Gotta say how great its been, i've been smoking for 7 years and i picked this up and haven't smoked since now! its been 2 months already and i don't miss a real *** at all buddy!
Awesome kit! heres the link to their site, give it a go! nothing to lose and your health to gain
Hope this helped
