I have used dozens of RDAs over the years and this one ranks super high as a dual coil rda. The flavour is superb, the airflow is perfect and with the beauty ring it can look amazing on most devices. Very easy to build on. The only downside might be that the ultem insert requires precision when putting the cap on and you can’t put massive coils in here. If you want to run 4mm diameter coils then this isn’t for you, but for everybody else, this is one of the best ever.
