Models (short for transitional models) represent the e-cigs that look and act very similar to conventional cigarettes. They activate when the user draws on the tip with his or her breath. Often, these devices or parts of them are disposable, semi-disposable, or easily replaceable. Chances are, if you’ve seen e-cigs in a convenience store, gas station, or mall kiosk, they were models.
Mods (short for Modified or Modifiable) represent a larger variety and range of electronic cigarettes. They are often a bit more expensive, offer a customizable (generally better) experience, and satisfy a certain hobbyist or enthusiast spirit in their users. Mods usually activate through the use of a manual button on the device. Some mods don’t even have a cylindrical shape to them. Currently, the mod community and mod market exists primarily online through various forums, custom order shops, and blogs.
There are products that blur the lines a bit between mods and models. Some models are being made with manual buttons while some mods are being slimmed down and simplified for introductory users. As the technology improves, both ends of the market will have their outliers and inliers.
