Best Bottom Airflow RDAs/RTAs 2020
Bottom airflow RDAs/RTAs are much more common than top-airflow RTAs or RDAs on the market today. Unlike top-airflow RDAs or RTAs that usually reduce flavor strength as some of the air goes directly to the mouthpiece, RDAs or RTAs with bottom airflow perform much better in flavor production because the air has to travel around the entire coil and bring all of the potential flavor.
If you are a vape enthusiast looking for an rebuildable atomizer for flavor, then a bottom airflow RDA/RTA is definitely a good option.
