I own the Zmax v5 and really want to try out a rda. Does anyone know if the Trident screws on to the Zmax V5? I know they both have 510 but I have seen vids where the Trident didnt fit all PV's with 510 properly. Any recomendations on rda's you know for sure work would be great. Just want to check before I spend $100 on something that wont fit.
