I use an ecig with a Vivi nova and the heads can be expensive to replace. I started boiling and dry burning mine and most turn out almost like new. It saves a TON of money. Rebuilding heads can also be a good way to save on having to buy more, too. While they're not really supposed to be rebuildable heads, they can be done pretty easily with a good youtube tutorial.
I haven't purchased new heads in a LONG time, and while I do lose a few in the process, it doesn't take very long and it's pretty easy.
