I recommend rebuilding them. The Kanthal is cheap, so are the cotton balls. I've estimated the rebuild to be about $0.03 per atomizer. Once your experienced with it, it's about 2 min a pop. If you are winding them for the recommended value of 1.8 - 2.5 ohms (32 AWG, 5 times around a 1/16" allen key), I've had some last over 2 weeks (12-18ml) of fluid. However, if you want a different experience with your vapor, grab some 28 AWG wire and wrap it 4 times around a 1/16" allen key. That will get you down to .8 - 1.1ohms. MASSIVE VAPOR CLOUD!!!
From other's mistakes, you must learn, young padawan.
Only run below 1.5 if you have a mechanical mod. DO NOT do it with an ego battery, I have melted two batteries doing that.

Make sure you are using "organic" cotton. There are some cotton balls that have been bleached. Yeah, you can actually taste the bleach... It is nasty.
