Hey all, so I bought a Protank-II today after using a Protank for roughly three months. Initially, the tank is sleeker and since the Protank-II comes in removable parts, it is easier to clean. I have also noticed that the draw is better (not as airy as the Protank). Another plus is that you can use the same coils as are used for the Protank and Evod. Thus far, I recommend getting the Protank-II. I will update this thread if I encounter any issues. I hope this helped, even if just a little. Please feel free to ask any questions regarding the Protank-II here. Also, I'm using a eGo-V v2 battery. Cheers!
