I feel like this may be a dumb question, but whats the difference between an RDA and its clone? Is one better than the other?
RDA.- Rebuildable Dripping Atomizer
RBA- Rebuildable atomizer
RTA- Rebuildable Tank Atomizer
Many vapers will never buy an authentic because they cant afford it. However, certain companies design their product in the US, but outsource the manufacturing to china, so these are authentics, just chinese made. These will be your best bang for your buck. This doesnt mean all chinese clones are of poor quality. In my experience, most clones work just fine and very few are poorly made. Do your research on clone companies such as tobeco, hcigar, infinate, ehpro, for example. Also, not every clone company makes every model the same. So homework on specific models, from specific companies, is an absolute must.
For someone starting out, buy a few clones, see what design you like (ie. external airflow ring, internal airflow control, high airholes, low airholes, side or top airflow, loose draw, tight draw, among other options...), before you drop money on an authentic.
