Customers who have been using an eGo, 510, cig-alike brands electronic cigarettes for a while looking to upgrade to something bigger and better, with more features, customizable options and something that can produce more vapor. This is where mods come into play. Mods are essentially larger, more powerful, more versatile, more customizable, higher-end electronic cigarettes. It is important to note that the “mod” typically refers to the actual device itself and not the atomizer, tank or drip tip. There are two major variations of “Mods”: Mechanical Mods (Mech Mods) and Variable Voltage/Variable Wattage Mods (VV/VW). VapeTreat brings top-of-the-line mods in Pakistan.
