You ask:
How do Vapor Cigarettes Work and why should I make the switch from tobacco to e-cigs?
Cartridges(atomizers) hold the filler which is soaked with a special liquid that contains the flavoring and your nicotine level.  As you depress the button on the battery the tank(atomizer) generates heat that vaporizes the liquid.  The User inhales the vapor which is smoke similar to the smoke produce by an analog cigarette.   Battery life is going to depend on how much you vape and  on the Battery Mah  (a 650 Mah Battery will give you approximately 600 to 650 puffs and last about 3 to 4 hours, a 900 Mah battery will give you between 800 to 850 puffs and last about 4 to 5 hours, 1100 Mah battery will give you approximately 1000 to 1050  puffs and last about 5 to 6 hours, 1300 Mah battery will give you approximately 900 to 1700  puffs and last about 6 to 8 hours) before have to recharge your battery.  We suggest that you let your battery completely discharge before recharging because your battery life is approximately 300 charges.  Some of the Mods (batteries) that use larger batteries can last for three days when fully charged but again this will depend on how much you Vape.
Analogy Cigarettes have over 3500 chemicals and over 50 known carcinogens. Most of which are cancer causing agents. Smoking really cigarettes not only effect your Lungs but also every major part of your system.  Vapor Cigarettes have 3 to 4 ingredients in them depending on which company you purchase from but that is still 99% less than an analogy cigarette Less chemicals, no lead, no tar, no arsenic,  no formaldehyde,  and zero cancer causing agents. While the damage already done to your lungs are irreversible it will not continue to get worse.  This says it all. 
Are Vapor Cigarettes Safe?
May people believe that the water vapor produced by the Vapor Cigarette usage is safer than the Analog Cigarette.  The relative safety of this smoking device is attributed to the ingredients used in the unit call E-Juice.  Users do not experience the persistent cough when they switched to Vapor Cigarettes, your sense of taste and smell improve.  And you are no longer a nuisance to the people around you because the device does not produce a thick and foul smelling smoke.  Typically, the liquid consists of Vegetable Glycerin or Propylene Glycol or a combination of both along with food grade flavorings and nicotine extract.  (Propylene glycol is a component used in several products including cough syrup, asthma inhalers, cosmetics and toothpaste.  While Vegetable Glycerin is palm oil or coconut oil. Nicotine  is a substance that can be addictive when taken in larger amounts, as you progress you can step down on your nicotine and eventually not have any in your Vapor Cigarettes at all.)

Can I Save Money on Vaping?
Yes you can save money on Vaping.  Your initial cost will depend on what Kit you start off with, At  AHH Vapors we have several different kits to choose from. But the cost of the kit will be made up in less than a few weeks or sooner (by not purchasing Cigarettes just think how much do you spend on Cigarettes a day, a week or a month). This will depend on what company you decide to use for your supplies. There are a lot of companies out there  and charge an arm and a leg for their products. But if you choose the right company,  you will Save.    Generally you can vape anywhere. You can even vape at work! I wouldn't recommend you make it totally known, but think about it. You can vape in the restroom, a closet or anywhere that you are kind of by yourself. It’s not a cigarette, so you're not actually breaking any company policies or rules. And Lastly remember you will also be saving your health. 
FDA has claimed these to be unsafe. 

The FDA has never said they are unsafe, they have only said they have not been proven to help people quit smoking, but that is why Sales reached nearly $500 million in 2012 and are expected to double to $1 billion this year. The "BIG TOBACCO Companies" have something to lose from this technology? Do you know where 95% of the FDA’s funding comes from? BIG TOBACCO Companies. It’s also not a conspiracy that BIG tobacco is a member of the board on the FDA, it’s a fact! You can find a scientific report done by New Zealand Health on the vapor and e cigarettes.
How much nicotine is in a Cigarette/Cigar:
Cigarettes can  vary in their nicotine content, one cigarettes levels can vary between 13.7 and 23.2 mg of nicotine per gram of dry tobacco as reported by the National Cancer Institute . The average cigarette in the United States contains about 9mg of nicotine, this is not the amount of nicotine that is ingested by the smoker. As cigarettes  are burned and the smoke is inhaled by the user, the nicotine is absorbed through the smoke therefore the amount of nicotine that actually enters the body in this manner is typically less than 1mg. Nicotine is the most important chemical element in a tobacco product. It is the most widely consumed substance and is considered an addictive drug.
Cigars contain between 100 to 200 mg of nicotine per cigar and that depends on how the cigars are and what they are wrapped with.
Because of the lack of smoke, e-cigarettes are considered healthier for you, however, you still will be taking in nicotine.
