New to vaping just three weeks. I got a Provari and love it. I also have a few Kanger protanks and love them as well. Easy to use good flavor and no leaks. I also have a Zatty Pro that I have not tried yet. My question is as follows: Would there be any benefit in trying other delivery devises as I am so happy with the Kanger Protank. Would I see a significant difference from the Kanger? If not I will put my $ toward juice and getting a nice mechanical to use with the Zap. Thanks Stu
