vivi minis are a win for me as well. I say that after using ONE vivi and two replacement heads for six weeks non stop. Here's some of my observations,
-My battery post has never been so dry.
-The draw feels just right for me, not too airy not too tight and the draw never changes. And you can take hard pulls off it no problem
-Big mouthfulls of vapor, more than I get from cartos. With cartos I was always craving that cigarette throat hit and never quite get satisfied. I find the thick mouthfulls of vapor I get from these to be a satisfying substitute and I don't crave that feeling anymore.
-nice warm vape.
-Nice and quiet, I can take or leave the snap crakle pop of a well working cato.
-easy to clean, easy to take apart, easy to dry burn, nothing really to screw up.
-they are juice pigs, the price you pay to have that much vapor in your mouth at one time.
-great flavor for me, but I don't think I fit into the category of a "super taster".
- the threads on the plastic tube won't last forever, mine will need a replacement soon.
-the two heads that came with it are still going. The one that I used most often has lost a number of the wick threads from all the cleaning, I predict I will have to rebuild this one because of the wick bundle thinning out before the coils stops working.
-I find them sensitive to juice viscosity. Too thick a juice and you'll say " these vivi's are crap". A little clear headed reasoning and some thinning out the juice and you'll say "wow, mind your juices captain what a difference"
A bit of flooding after topping off the tank almost every time, I fill only to under the wick. Occasional flooding at random times, but not to an annoying or fatal degree ever.
-9 dollars 99 cents for six weeks heavy and constant vaping and still going. I went through seven cartos in that same time. Not because I used the cartos more but because FIVE of them didn't work out of the package. The two cartos I got working were not in heavy rotation for this period, an occational toot here and there.
I'll end my vivi love letter there.
Did i mention the potential to rebuid the coil for pennies?
