Just like traditional tobacco cigarettes, you'll become accustomed to a certain taste of e-liquid for your electric cigarettes, or you may even enjoy a couple different kinds. Most first time buyers just purchase a standard tobacco taste or some choose a standard menthol flavor, and then of course the smoker gets to choose how strong the e-liquid is, so that's basically like choosing whether the cigarette is a full flavored, light, or regular flavored cigarette. If you choose to use electronic cigarette refills instead of disposable cartridges, then you'll find that there are many different flavors of e-liquid and you may want to try some different flavors or strengths every time you need to stock up on supplies for your electric cigarettes. Amazingly, there seem to be more flavors in e-liquid than there are in regular tobacco cigarettes, with flavors like cherry, chocolate, vanilla, strawberry, apple, and others. That's one reason why people like the electronic cigarette refills, so they can try out a different one every time or maybe order a couple of each flavor to be able to experience something new, perhaps buying two or three different kinds of e-liquid.
After you've started smoking electric cigarettes for awhile, you'll also learn whether or not you like electronic cigarette refills or disposable cartridges. With disposable cartridges, you'll have to throw them away every time they run out of e-liquid. Some people find this easier to do than to have to refill them themselves every time. Also, the smoker needs to be very careful if they choose to refill the cigarettes themselves, because if they were to spill the liquid nicotine on their skin or hands, they could get extreme nicotine poisoning because it would be absorbed so quickly through the skin. So make sure before you order these, make sure that you're up to refilling these.
Many smokers become afraid that they're not going to be able to enjoy the flavor of electric cigarettes, and they often come out surprised when they see the number of options they've got!
