If I could recommend something to you, I would say that if you are new to using electronic cigarettes try to steer clear of the tank system.
They do work well in a lot of aspects but typically tend to leak liquid for a number of users.
Great concept from Joye, I just think they were released a little too soon. If you're tech savvy and don't mind using a small pick tool to adjust the wick material inside of the atomizer every 4-5 days, I would say to give it a try.
I would say the same for anyone looking into the 510-T systems.
DO NOT use the tank system if you have automatic batteries, I know this is uncommon in the eGo kits but there are some knock off eGo kits out there that actually have automatic batteries. Automatic batteries are more commonly seen with the 510 systems but either way, if using automatic batteries do not pair with tank system. If your tank atomizer decides to start leaking through the vent hole on the battery side connector, your automatic batteries will most likely no longer function.
