I got an eGo One Mega tank bundled in with my evic-VT. Don't like it. The gap in the tank to add juice is a lot thicker than on the regular eGo One tank, so you can actually fill it with a dropper and don't need a unicorn tip or a syringe. However, the wick holes on the coils are so small, I was getting dry hits galore with it, even with a nickel coil in it.
