I was frustrated with the Nebox...so I sold it and bought an Eleaf Basic Kit...much better to carry around...not as heavy and easy to fill. However, only holds 2ml.
I just can't deal with the lack of air flow. Nice box if you're more mouth to lung, or maybe a step or two above. But I'm accustomed to the TFV4s and Crius wide open, so the Nebox was a bit lacking.
