Really?
I've been vaping a while now and have an array of mods I can use some mech, some regulated and 9 times out of 10 I reach for the ZMax I have.
Mechs are great devices and a lot of people prefer them, but they aren't a one size fits all. I have 20 or so local regular customers who have tried a few of the things I have here and still prefer their eGos.
There isn't a lot of difference between a vamo and an iTaste V3 vape wise. The vamo is bigger and takes bigger batteries and a ProTank sized atomiser will look better on top of it.
If you are going for a Vamo get a v5 and not a v2. You have a choice of a Vamo a ZMax a SID an SVD or an MVP for a regulated mod - they are all roughly the same price and they all do more or less the same thing. Which one is best for you comes down to looks and your exact budget.
