Amanda from Detroit, MI reviewed Vapor King model 'Manual' on March 26 2011:
OverallIt's an amazing idea and product. The only downside to this brand is the battery life. It died before I even finished a cartridge. I like having to push the button. I would recommend the manual. I hope I don't have to buy a new battery I'll be very angry and probably switch to a different brand. I wish I had read these reviews before purchasing..
