Received my spare plastic tank from madvapes (super fast shipping btw, ordered late Friday & was in my mailbox Monday morning!). My viva is the aClear clone, several vendor sites that sell aClear had replacements tanks with verbage saying it fits only aClear, not Viva Nova. Don't believe it! The viva nova tank I received fits my aClear perfectly, no leaks. Only difference is the markings stop at 250ml, and it says Viva instead of aClear Variable. Also like that I have a colored tank now, easier to figure out what juice I have loaded in different tanks.
