I'm currently sitting here... thinking over the time since I received the v2.5 Viva Nova last Friday and while I had noticed... I really hadn't paid attention to how much of a non-issue using and maintaining them have been for me, unlike all of the other CE2 type vaporizers I've used since I started vaping.
To fill... unscrew the top and fill... scew the top back on... nothing more
Very good flavor... not great, the flavor isn't completely even and they do accent the high notes as Briar pointed out... but still very good.
My all v2.5 ( both of them currently ) haven't leaked any... I've never had that before with anything I can recall
To clean.. take off the top and the tank, unscrew the head and toss it into the alchol, rinse everything else off, replace the head with another and put the tank on... fill and replace the top. After the heads soak for a bit, rinse and dry burn them and put them back into the rotation. The disassembly, rinse and reassebly takes maybe a couple minutes and rinsing the heads and dry burning maybe a couple more at most.
This is how I always had felt it should have been all along. I find none of it fiddly in the least. I am also really looking forward to the new version of the Stardust so I can get a batch of those for the juices I don't vape as much and to not have to worry about them leaking while they sit until I get into the mood for some of them.
That is all... I'll return you to your regularly scheduled thread now...
