I'm currently stuck between the Tesla, the Vamo V5, an the iTaste SVD. Done so much reaing my head is going to explode. They seem about the same, almost like splitting hairs. I won't be sub ohming but would like to start building coils for RDAs (likely the Immortalizer), but for now just using a Dabbler top for oil. Think the Immortalizer could work well for oil or juice, but I digress. Likely 80% of it's use will be concentrates but I WOULD like to stop smoking cigarettes and start vaping juice instead so that's a consideration too. I don't wanna spend a ton either but don't want to cheap out like i have with eGo batteries either lol. I'd like to avoid Mech MODS for now so what would ya'll pick and most importantly WHY?? Thanks for the input BTW al!
