My wife has a ProVari, I have a VAMO, and a SB w/ kick. These are mine and my wife's opinions. We do not like the VAMO, but it does work. It is possible I just have a bad mod?
-I don't think the settings are accurate, in RMS or AVG. They may be closer in RMS mode, but I have to turn my voltage and/or watts lower on my VAMO compared to my kicked SB or my wife's ProVari. As a matter of fact, without the kick in my SB, I vape great at the battery's 3.7 and my VAMO I have to tune it down below 3.7v or sit around 4-5w sometimes.
-I am not an electrical engineer or even really know what those modes mean compared to how other things work, but my experience is PWM is not for me. The vibration of the PWM bothers me, definitely not the same vape you get from a ProVari or mech mod.
-Buttons changing settings OFTEN in my pocket or if i set it down and it gets bumped. If I pick it up I can get my head blown off or get a tiny bit of vape. its a 50/50 chance if I don't check it and reset it.
-Battery cap comes undone OFTEN, reset your settings as well. Nothing bothers me more than picking up my Mod for it not to work and I have to fiddle with it.
-clinkity-clink: everything rattles on this mod. Its like picking up a maraca. (exaggeration i know lol)
If you have the money, and want a solid performer... provari or kicked mod wins hands down. If you are hard on cash? I personally would recommend a couple of Twists over a VAMO honestly. If someone wants something to tinker with, or to have a large shiny mod regardless of its shortcomings, 60 bux is a good price but i think its probably worth about 40ish.
Before yall hate on me.. like i said, we just dont like it. Build quality is bad, PWM is weird, doesnt work 1/2 the time without fixing something. Just not a quality product and that's why they make a profit while selling it at 60 bux. =)
