Hello fellow vapers, i would like to share my thoughts and experiences with kangertech. Here is the issue that i have with my protank 3, aerotank mega and aerotank giant: THEY ALL LEAK VERY BAD, I cleaned the whole thing and even put a new coil in and only fill it half way and as soon as I take the first draw it gurgles and spits juice in my mouth. And at this point I'm ready to throw the towel in regarding kangertech products. So if anyone had these issues and know how to fix it please let me know, cause yet again I'm back on my twisp.
