I started with the EVOD kit as well and it did it's job, got me off cigarettes. It's a good kit IMO.
My only regret is if I could have peered into the future and known it would work, I would have skipped it and gotten something like the MVP 2 (or even a higher wattage device with a replaceable battery) plus a Kayfun rebuildable tank instead of 'moving up the latter' sorta speak (as many have).
