just started a few months ago....made some pretty big investments (end year bonusses spend [emoji38]) , I don't want mechs, so going for higher quality devices. But now I'm set for a long time with:
- 8 liters of 36 mg Nic (I vape at 6mg, will last me 10 years)
- 15 liters of 0mg Nic (I assume this will still be available, but it will keep between now and when it's used, so I thought to be safe and have a little stock just in case)
- 13 Mods (of which 6 are dicodes, 1 Sx Mini M, 1 original Xvostick and 1 Provari Radius) rest are 2 clone xvosticks and 2 heatvape invaders. My GF also has another 6 mods
- 7 Kabuki's (4 original, 3 clones), my GF has another 4.
- 10 goblin mini's (8 original and 2 clones)
- 250 Nauti coils
- several 100 feet of wire and a stack of cotton
sold all my other stuff...sticking to the tanks/RTA's of the same make, they hit my sweet spot and this way I only need 1 type of coils and spares.
I'm all set now, and don't really feel the urge to buy more

Feels good to be prepared for al eventualities.
