The eGo-C or eGo Twist are great entry level setups. They are incredibly affordable and work great! Find one that has the "pass-through" option and you can even use it while it is charging. Along with that, I recommend getting some low resistance cartomizers and at least one atomizer. The atomizer is useful for trying new flavors as you can just direct drip and couple of drops onto the atomizer coil and try out the flavor. This helps prevent wasting cartomizers on flavors you don't end up enjoying.
Once you've identified some flavors you really enjoy, I would recommend getting a cartomizer tank, this will hold a lot more liquid so you won't have to refill as often. Just make sure you like the
juice you're putting in, haha. I currently have 4 cartomizer
tanks that I use for my favorite flavors so I can switch between them with ease and I always have my atomizer in my case so that I can try new things. Once you get the hang of it, it gets really easy to manage. Happy
vaping!
