I have to admit I was shocked to hear of a Protank 3 so soon coming off the heals of the Protank 2 and Mini 2, and the Unitanks but then when I heard what the change was I couldn't wait to get my hands on one. Fortunately my usual first go to had just gotten them in stock, and two days later I was vapin with my new Protank 3. I was glad to hear, just as it explains in this Protank 3 article, that nothing really changed except the replacement coil of course and the base which had to be adapted for the new coil head. I thought that was a good thing that they can use almost all of the same parts so if something happens to one or the other, it's not a complete loss. Upon first vape I was pleasently surprised that the vape was warmer, more like a top coil, and of course the flavor was good as with most bottom coils, but the vapor was nothing short of spectacular and I am glad I got one even this soon after the others, and I highly recommend it to anyone on the fence.
