Vape Pens have become a bridge product between the cig-a-like ecig and the Vape Mod. Most smokers will generally go towards the cig-a-like units because they resemble something they are used to. In most cases the smokers end up with something that almost gets the job done, but still leaves them unsatisfied. When this happens, the smoker either just keeps on smoking, or they upgrade to the next level – the Vape Pen. As you will see listed below, there are several options to choose from and to be honest, in this category (Vape Pens), the products are relatively similar. The only difference can be found in flavor selection and nicotine levels, because they all generally have the same hardware makeup, unlike their cig-a-like predecessor.
