I hope I bought a reputable brand that will be easy to use. This is my first e-cig purchase so I have no idea what to expect. I only want to have a device that satisfies my smoking pleasure without a lot of complicated doo-hickies that need constant maintenance. I hope I have made a good choice and that I can substitute the Safe Cig for the brand I have been using for 25 years. Does anyone have good input on the Safe Cig?
