I've been using the DPro RDA for like 4-5 months and it has been my favorite RDA after the day i purchased it. First of all it has a great & easy to use build deck. Secondly, it does produce a great flavor.
The only con with DPro i can mention is that, if you over prime it with juice, the screw holes eventually can be filled with juice and get leaking.
I've used it with both my Drag and a VGod mech pro, it was all great with them.
