As “editing this guy” said, the 909 Dot RBA never promised me a mouth to lung, so I’m not counting the lack of one against it. The flavor on the 909 DOT RBA is just straight up bangin good. The airflow feels as smooth as it can in the DotAIO. Building and wicking on the 909 Dot RBA deck are both stress-free experiences thankfully.
55 for the RBA isn’t terrible, but others with similar experiences are up to 10 cheaper. Your mileage may vary.
