A have all 3, and really like them all, they all have a place in my rotation!
Provari where he constantly showed the unit putting out consistent voltage irregardless of discharge state, which is what I am interested in.
Yes ... a Provari is a good PV, and worth what they cost. No ... the Provari is not the only show in town. Just remember that YOU are the only person that your PV has to satisfy.
Some mentioned the Kick as being just as good. Matter of fact I've been using one this morning instead of my Provari.
Silver Bullet = $85
Kick sleeve = $25
Kick = $45
Provari = $159
OP asking a specific question-
"Has anyone put a itaste vv 3.0 or MVP 2.0 on the scope and monitored it's output over the discharge cycle?
If these batteries do "sag" during the discharge cycle, then the voltage regulation alone appears to put the Provari in a league of it's own."
I own an MVP 2 and it's great when the battery lasts. There are quite a few posts about the fact that MVP puts out nearly identical voltages as the provari, but without the benefit of the same output voltage through the life of the battery. The provari uses an 800hz signal and the MVP does not use the cheaper 33hz signal that most other mods use. The provari is also on my wish list but am holding out a little bit until the sale that is supposedly happening later this year?
pbasardo does put these on a scope so those links above should provide the exact answer you are looking for.
As all three of these really are ideal for different reasons, I am not speaking form a "better or worse" aspect.
The iTaste 3.0 simply is too small a battery to effectively hold its output despite the circuitry designed to do so and you may indeed notice a small (not major) drop off as the battery depletes.
The Provari's well-deserved claim to fame is that it simply is built to a very high standard, which to an extent justifies the lofty price tag. It is not really an up to date device in terms of features, but for many the great build quality alone is worth the price.
The MVP 2 may be a great choice as it matches the iTaste 3.0 features, but with a 2600mah battery, keeps a more constant "hit" throughout its run time.
I have and use both the iTaste 3.0 as well as the MVP 2, and they are both great devices. The iTaste 3.0 is simply a more "carryable" device for me, but the MVP 2 I prefer for its great all-day plus run time.
Don't have a Provari, but have used one and they are indeed nicely crafted mods!
