There really isn't an EGO VV - it's not variable - its selectable! I think we should be a bit more specific here. There are only 3 voltages to choose from with the eGo battery.
Shouldn't we be talking about the pros & cons of purchasing a eGo Booster?
Variable by definition just means changeable, so it is variable voltage. As in, you can change or vary the voltage. Thing is, most people that are even going to consider buying these are big eGo fans (otherwise they would just get a VV box
mod or something similar, and more than likely for a lot cheaper, too). So if they're eGo fans, it's also worth them knowing that they can
buy an eGo battery instead of just adding something on to their current one (that adds quite a bit of length and weight) and still be able to vape at the more popular voltages at a third of the price.
I just think it's worthy of discussion. I don't think that we can ONLY discuss this one thing here and can't compare it to other, similar products. But hey, that's just me.
