I also wish the Vola tank came with an RBA. Other than that, I like the size, weight, rounded corners and the metal textured buttons have a high end feel to them compared to clicky, plastic buttons. If you have a 2ml version, you can remove the rubber stoppers under the cap to make it 4ml capacity.
The TFT screen is also clear and easy to read. The runner icon looks cool, but you'll never see it while you're vaping because it resets when you release the Power button. I think a Digital Clock would be a much better feature. Overall, except for the short battery life, I like this little mod and sub-ohm tank combo.
