you and your husband plan to share 1 e cig?
I recommend you both get your own kits. 2 ego twist batteries, 2 chargers, and 3 clearomizers each.
If you want to try cartomizers or cartomizer tanks, get 1-2 of them as well if you can.
But yes, ego twist batteries are where its at these days for new vapers in my humble opinion.
Although there are many other great options such as value priced mods or even regular ego bats.
1 person cannot survive on 1 battery alone, no matter what size it is you should have at least 2.
I would personally say at least 3 but if you want to buy your 3rd at a later time you can do that.
Get yourself and your husband 2 ego twist/spinners each, the chargers, make sure you get ac adapters for the usb cable.
then get yourselves the kanger T3s or vivi nova minis or smoktech redux or vision clearomizers, 3-4 each will be best.
Then get yourselves some juice. 12 and 18mg so that you can figure out what level of nicotine you like best.
If your going to want to vape a lot, 12mg. If you want to take 5-10 puffs then be good, 18mg would be best.
Its also best to buy a lot of small bottles of juice rather than a few larger bottles of juice.
You might get the idea that your really going to like a flavor, and then when you get it, its not what you thought itd be.
good luck on your vaping journeys
