The MVP is a battery. You can exchange Clearomizers (tanks) and some RBA will work on this device but it will have some restriction when you are building your own coils. If you do use a clearomizer this device is perfect.
You should consider joining the vape meet in JHB on the 14th of June to meet all the forum members and see the setups available. You will definitely get great help and an idea of what you would want and can afford. Suppliers are also available if you want to buy on the day.
