I'm retired at 62. 3 months back on Nov 5th I had my last cig after 50 years smoking heavily. I've blown $1041 on Vaping in the 3 months, as shown below.
I love vaping instead of smoking tobacco; and my body, friends and family love it too! Its real relaxing.... indoors, where you like to relax!
Theres a learning curve. The forums help but it takes time to make sense of all that info. Hope this helps someone save some money/time.
I wish I'd only bought the items in bold italics, totalling $380. Oh well.....
Liquids aside, all you need is a ViVi Nova and a Vamo battery set. Or equivalents. Plus cotton wick material and Kanthal wire.
Liquids: its cheaper to buy the VG, PG and Nic liquid in big bottles. I reckon what I have below in yellow will last me (a heavy vaper now

a year or 2. I might need more VG,
but thats the easy one....Walmart, cheap. Careful with the 100 mg/ml Nic liquid expiry date, and keep it off your skin while mixing.
Flavors. Walmart liquid food flavors works. The ecig suppliers stuff on-line works better but the snailmail gets old. Its a matter of taste preference. Suck it and see

Theyre cheap, and its fun.
Use 'ejuice me up' calculator for mixing recipe calculations... works real good. Round all the numbers.... it aint rocket science. Use a 5 ml syringe and glass dropper bottles.
The cotton wick material below works real good in the ViVi Nova only IF you cut little V notches in the rubber cap that clamps down over the wick holder.
Otherwise that rubber stops the liquid flowing along the wick thro the coil. Forget silica (glass fibers in your throat/lungs?). Forget SS... its conductive! Use this cotton.
Theres rewicking, recoiling videos on Utube for rebuilding the ViVi Nova. Its a piece of cake.... I use no tools at all now, just fingers and nails. Takes 5 minutes which
is just as well because a cotton wick is only good for 2 full tanks (6ml) then, like all wicks, you replace it or fiiddle around cleaning it which takes longer than fitting a new piece.
If you insist on cleaning it 'in situ', scrape it gently with the sharp tip of a box knife to get some crud loose then wash under tap. Check for short circuits before firing up!
Tips: When new, boil the cotton spagetti in bulk then dry; totally soak the wick in juice before filling the tank; flame the wire so it wraps 5 turns easy and loose on a paper clip; no dry burning,
shake your liquids frequently and keep 'em cool; if you disturb a coil always meter check for short circuits before connecting to any battery,
throw away the stock ViVi Nova wick material and coil, and especially the little fiberglass insulator they put in there over the coil to stop shorts. Glass/Silica in wicks (lungs) is a no no IMHO.
I like cotton candle wick because its tight weave keeps particle shed minimal (I've checked with a 30X glass). Sure there are better wickers.... they shed sharp ...., or short...or something
My theory is that a) less shedding is better b) soft, boiled, natural fiber shedding is better than hard/sharp because it should cough up more easily.... hairball! U gotta better theory?
Because I bought the Greensmoke gear first, I leave their stuff in my car and boat and use their USB/12v adapters. It is so convenient... no batteries, good cartomizers, little particle shedding.
Greensmoke is nowhere near as good a vape, and expensive, so if I hadnt rashly bought that stuff I'd be pocketing my Vamo/Vivi for the car/boat...everywhere. I don't much trust readymades.
By the way, you can condom refill Greensmoke cartos, or pop the tight white cap and drip refill. But not if youve had 'burnt' taste already... it lingers. I open unburned ones and boil them, then dry.

Note: I intended the IPA for cleaning battery terminals but never used it. Non-lubed kleenex on a cotton bud and/or plastic flossstick works for me. Never use the pipe cleaners either.
Note 2: stick to glass bottles, theyre cheap.... all plastic/poly bottles give off crap with temp & time.......and this stuff is heading for your lungs/blood not your guts!
