hello, I've been vaping since December 2015. My first mod was eGo one, I liked it but I wanted something with RBA so I bought a Kangertech mod. Everything was awesome for at least 8 weeks. Then I started to get burnt hits, I changed the coil, changed the juice, tried to add a VG, still tasted like crap.. So I bought a new kangertech tank... The problem was still the same... So I bought a shole different mod - the vaporesso 75w target, because I've read awesome reviews.... But I'm still getting burnt hits, its awful. do you think that the problem can be in the batteries? Because I have two of them (both since January) and that's the only thing that these two mods has incommon. I'm pretty desperate, I used to love vaping, I stopped smoking because of it. thabks for your help!
