oh how I love my vamo. VV is awesome! For me, I still rock around 3.7 v most of the time for a couple of reasons. 1)when I vape over say 4.5 volts I get a sore throat because I think the vape is a little too hot and also causes my lungs to hurt because I have absolutely no restraint and vape constantly. 2) I like a lot fruity vapes and typically they don't do well at high voltage. Barring these 2 issues that I have I love vaping hard, strong and having reckless throat hits which are all possible with a VV and would vape like that all the time if I could. Now the question is do you need a VV? Short answer is no. There are plenty of other units out there that will give you a stellar vape experience but a VV is nice to low to 0 nic. It took me a long time to finally get around to taking them out for a spin and honestly I am so glad I did. I love the vamo because its reliable and honestly, it dirt cheap. A kit runs around $75 but if you already have batteries and a charger you can pick one up (Tube only) for as low as $35. Thats a price you just can't beat for a solid VV mod. I love that I can crank it out or vape it like I do my silver bullet (no kick.)
