A number of electronic cigarette users prefer to drip e liquid onto their e cig atomizer instead of refilling the electronic cigarette cartridge. This method is known as dripping. Many e cig users believe it produces better vapor and gives you a better throat hit when vaping your electronic cigarette. If you choose to drip your e cig, it will be easier to do with an e cig model that has an enclosed atomizer such as the 901 series. If you use an e cig brand such as GreenSmoke that has an atomizer contained within the electronic cigarette cartridge, then you will need to use an alternative method to refill the cartridge with e liquid.
If you use an e cig model such as a M401 or Pilot series that is exposed, then it will be more difficult to drip fill your electronic cigarette. The mesh bridge of these atomizers is exposed and projects upward from the atomizer casing. These atomizers do not have the same tube walls to channel the e liquid drops when you drip the e liquid into the atomizer and can prove more difficult to drip fill them.
