Your Vivi's are fine... if your going to spend the money on something else, Do some research, or go to a vape meet to see what others are playing around with...
I hate the taste of cartos, so i wouldn't recommend them. But who knows, you may like them...
If you want to try your hand at rebuildable geni-style tanks, there are units for $30 that you can play with.
no need for the $150 price tag, if you are unsure you will like it... And if you are in love with the setup, then get the ZAP.![]()
I agree. Genis are not for everyone. Get a cheap geni and try it out first.
