The VAMO is a solid device which I have used extensively for about three months now - I have used Vision Vivi Novas, Vision clearos, Kanger Protanks, Kanger Evods, X10 (Fasttech), and I have played a little with an AGA-T2 and AGI. Net of it is with the flexibility of the variable volatage / wattage, you can get just about anything to run well on it. (As long as you don't use low ("sub") ohm atomizers.) As noted in the earlier posts, the attachment options are good (510, eGO, etc) and the ability to select wattage males it a pretty flexible device.
