Thank you VooPoo! Looking at the description of the products this is the reason why VooPoo is one of my favorite brands. If I'm correct and I'm reading the advertisement correctly this brings together all of the coils in compatibility. Meaning this product when I receive it will allow me to use the 15 boxes of PNP coils I have plus my RBA. And give me the opportunity to purchase the newer coils to compare them. If I'm reading it correctly that is amazing. That is how you get people to continue to be customers of yours for life because it's very frustrating having to constantly buy brand new coils for every new device and then the companies move on to another device and pretty soon the coils aren't on the market anymore. Or you can't get them at your local vape shop anymore. If this can actually accommodate any coils from the original PNP line including the RBA on up to the new coils specifically for this device that is a game changer.
