I anxiously waited and received the Atlantis Mega only to find out it doesn't fit on the ESP mod. Two new products that don't work together and I have to purchase yet another mod to use it? WTF. I have all these Aspire tanks and batteries where I was hoping I would just need one mod! Now I got a useless Mega tank until I purchase a mod. Which at this point I'm leaning towards other companies! I was really happy with my products until now.
