Each e cigarette device generally comes with a rechargeable battery, an atomizer, several cartridges filled with liquid nicotine, and a battery charger. When you take a drag, the atomizer heats up turning the liquid into a vapour and giving you a hit of nicotine.
You simply change the cartridge once all of the nicotine has been used. Each cartridge is equivalent to 1-1.5 packs of regular cigarettes, so this device will save you money. An average pack-per-day smoker, who makes the switch, will save up to £3000 each year.
Types of e cigarettes available
There are several types of e cigarettes on the market. First, some brands combine the atomizer and cartridge making the main device two 
pieces instead of three. These artomizers last longer than typical cartridges and because you are replacing the atomizer every time you replace the cartridge, your smoking experience will be more consistent.
Second, consider how much vapour you want. If you are a regular smoker, look for a brand with a good-sized vapour hit for the most realistic experience. But if you are used to smoking light cigarettes, choose a brand offering a lower level of nicotine.
In addition, some brands offer a manual battery switch that will give you more control over the amount of vapour and make your batteries last a bit longer between charges.
Some brands also have USB battery chargers that plug right into your computer. Also, most brands offer a variety of flavored cartridges. Typical flavors to choose from include tobacco, menthol, vanilla, coffee and chocolate.
Most popular
Because e cigarettes are becoming more popular, there are a number of good user reviews out there. So, you should check them out for yourself before deciding what to buy. But three of the most popular brands in the UK at present are Green Smoke, Sky Cig, and E-Lites. Green Smoke has been on the market the longest. They use VG, which gives the vapour a sweet taste that some users enjoy and their cartomizers last a long time. Some say Green smoke is the best at simulating the flavour of regular cigarettes.
Sky Cigs offer the latest in e cigarette technology. Their new model offers the most vapour per drag and has been rated as most similar to the tobacco cigarette experience. Finally, E-Lites earn points from users because they have a very realistic feel and come in a pack that looks just like a regular cigarette pack.
They also have eight cartridge flavours to choose from and all flavours are available at different nicotine levels.
