How do you think about X CUBE II?

Do  you a vaper at first? If yes, please go on.

I heard SMOK's new box mod: X CUBE II which is 160W with temperature control and two replaceable 18650 battery. How do you think about it? Is it worth to buy?

My co worker has one these, it works really nice but a lot of it depends on if you use a tank for dripper (RDA). I'd use RDA with this battery.
