I have been researching VV mods here and other forums and came to the conclusion that the Provari is the best. The second best is the LavaTube. The Provari only beats the LavaTube because the display indicates the voltage you are using for that specific atty. The LT does not but just as the Provari it adjusts to the correct voltage to keep it at 2.5 amps max. for protection.
The big diffs is the price. Provari is twice as expensive as the LT. So buying the LT is a no brainer.
The LT is sold rebranded as MVari, Torpedo VV, Vision Tox VV and more.
Now eCiggies - Electronic Cigarettes | Vaporizers | e-Liquid | Electronic Cigarettes | Electronic Cigarettes will be selling it as LavaTube from end March. They have completed their test and will soon put it on their website.
