Halo also was the brand that succeeded in helping me quit smoking when I was in the same shoes as you, I chose to go all in with Halo... and I regret it now that I know more than I did then. I have multiple G6's and Tritons but I have been less than satisfied with their tanks. I ended up getting a SmokTech SiD and an Ego and I can pick up a tank or clearomizer about anywhere I'm at in a pinch because they use the most common threads, I can experiment with all sorts of tanks/clearomizers, and I have found ones I like a lot more than Halo's. I wish instead of diving headfirst into Halo beyond G6, that I would have just went to Ego instead and set the G6's aside for emergency. Now I have these Triton VV's collecting dust alongside them. They are great batteries, just not many options with them.. and I like my options.
