The battery is the same size as the iStick 40W TC. The tank, even though it is 5ML, is shorter and wider, and is a lot more cohesive. I think that, since it is more squared, it feels better in the hand, and seem a little more solid to me. Without the tank, the iStick 40W is more rounded on one side, and a bit lighter. Maybe the extra 40 watts weigh more. HA! Just kidding. It feels like it uses thicker metals, so that may be the difference in weight.
Here is my black Cuboid Mini, next to my black iStick 40W TC sporting a stainless Cubis tank.
Here is my silver Cuboid Mini battery, the iStick 40W TC, and the VTC Mini. The Joyetech VTC Mini was the battery I used the most, before the Cuboid Mini sample kits arrived.
We should be getting the Cuboid Mini kits soon, in case you are interested. I love these things!
