What are the benefits of RTAs?
The major benefit of using an RTA is that it gives you the freedom of building your own coils along but with the convenience of using a tank.
Unlike a traditional vape tank with pre-built coils, an RTA is much less expensive to own because kanthal wire and organic cotton are both very affordable when purchased in bulk. The cost savings of using an RTA can be considerable if you typically buy e-liquid that's heavily sweetened. Sucralose leaves so much residue on a vape coil that you might find yourself wishing that you could replace the coil in your tank every day.
When you use an RTA, you can replace your coil whenever you like without worrying about the expense.
What Are the Drawbacks of RTAs?
The main drawback of using an RTA is that it requires all the effort of using an RDA without any of the performance benefit.
While an RDA can be capable of producing enormous clouds if you're willing to put in the time required to build more complex coils, an RTA will give you roughly the same performance as the tank you're using right now.
Vapers don't really use RTAs for their performance; they use them because they're tired of spending a fortune on pre-built replacement coils. One thing to consider before you buy an RTA, though, is that your time also has value.
When you use a tank with pre-built coils, unscrewing the old coil and screwing in a new one takes only a
few seconds. Building a coil for an RDA or RTA, on the other hand, takes several minutes, even if you're an experienced coil builder. You should budget around 10-20 minutes for building a new coil - and that's if you don't make a mistake during the building process. Errors often mean that you need to start over from scratch.
Switching from a traditional tank to a rebuildable atomizer always means that you're committing to make a significant investment in time on each ocassion that you want to rebuild your coil.
