A SteamLite Electronic Cigarette is formed of 3 major parts namely a Battery, an Atomizer and a Cartridge Refill.
When you take a puff or when you smoke from the mouthpiece of the e-cigarette, the Atomizer releases a small amount of the E-liquid which contains Nicotine through the mouthpiece and the tip of the battery or the LED will glow red.
This E-Liquid consists of a small amount of propylene glycol due to which the Electronic Cigarette will release a colourless and odourless vapour while smoking which is harmless in comparison to the actual smoke of a normal cigarette. This gives the Smoker a feeling of “smoking” a Normal cigarette minus the harmful smoke coming out of it.

Unfortunately we have found that the three piece electronic cigarettes don't work as well as the new 2 piece ones. The 3 piece is usually made of inferior quality parts and needs cleaning.

People using e-cigarettes usually don't want to mess around with having to give maintenance to their e-cig and that is why we give more points to a 2 piece than the older style 3 piece ones.
