So I have had the NEBOX for about a week. I have used it exclusively for that time. I am using the RBA head for it and experienced no leaks so far. I am not really a fan of TC and I have not used on this tank so I cannot speak to that.
This tank does have it's compromises. The plastic Tank. My ADV is a borderline tank cracker. It has a hint of cinnamon in it. I have had good luck with other plastic tanks I have ran it in, and so far so good, but we shall see. I am a little bummed that I cannot run my other citrus and cinnamon flavors in it, but that is what other mods are for
I found a Efest 3100mah 20A battery and with a .22 coil at 20 watts I am seeing 24 hours of use on it, which doesn't quite empty the tank but it is enough battery life that this has been working for me for a daily driver. Anything less and this mod would have ended up on the shelf as the batter door is impossible to use. On board charging is good about 3 to 4 hours from empty to full charge.
Cleaning has not been an issue so far (note I have only done it once). As long as you are careful, turn the water on slow and make sure you dump it out way from the electronics in the mod, no problem. I did see that Kanger made a silicon sleeve to cover up the rest of the mod. It would have been nice if they would have included it with the mod though. I have not picked it up but i may.
The Vapor produced is just like the sub tank mini (at least with the RBA head) and IMO those are once of the best tanks out there.
Time will tell, but so far this has replaced my MVP 3/Subtank Mini as my daily driver with that setup riding in the bag as a backup.
