Well you forgot the Golden Rule ! ! !
Always Have Backups, and Backups of Your Backups. 2 EGO's and one charger for as long as you have been vaping is a poor setup (I have a LOTS more than that & several chargers). You should have tripple that at the very least. Yes to start, to see if it is for you, 1 set of batteries and 1 charger is fine. But once you see that this is what you want, order another set & charger. Then after a month or so order another set and charger (savings from NOT smoking will pay for these). Then if you want to venture to some of the mods or something, great. But always have backups, and backups of your Backups. This also applies to cartos, tanks, EVOD,s, coils, etc, ALL YOUR HARDWARE AND JUICE. I see posts all the time of someone with this going bad, or running out of juice, and NOT having backups. It is not like smoking where you can just run to the store to pick up another pack of stinkies. And NEVER order from FT unless it is just for spare/backup stuff that you won't need for over a month. I was upset with my FT order that took 47 days, but I had plenty of stuff to keep me going, I was just upset with how long it took, not that I needed it today or I would go back to the stinkies. If you are going on a long drive do you wait until you run out of gas and then gripe because there is not a station close? Come on, always be prepared for what life craps on you.
