You will get all kinds of advice here on what to buy. Some good, some self serving.
I can tell you what I've gone through.
I started with an e-cig from V2 cigs. small cartomizers, refillable, small capacity batteries. That was in the middle of last November. My wife uses them everyday still, and the equipment is still going strong.I am still in fact refilling the cartomizers that came with the original kit. to me that's mileage.
I graduated after that to a T-Rex.I loved that because I could screw more stuff on to the end of it and that changes the flavor of a juice as well as how long you can go before you need a re-charge.
I have purchased and used a few "e-go" knockoffs. I have not been real happy with any of them. when you get a cheap knockoff from an unreliable source, well, you only get what you pay for. The button sticks on two of them, one broke right at the joint between the battery and the button housing and one just plain quit working.
TIP, buy the best unit you can afford, from a forum recomended supplier and you will be more satisfied. at least if you have an issue with it you are more prone to get better customer service. If you are thinking about a particular brand or style see if there is a dedicated thread here. I know there is an EGO thread, there is probably an 808 thread.I know you have no idea what that means, I want you to go look.
I have also tried a lava tube type unit for a short period. I had to send that back for a trade and will receive a new one with safer batteries. The jury is still out on weather variable voltage is worth all the hype, but from what I could tell, it probably is.
as far as "does it taste like a cigarette", well, no.
nothing tastes like the burning tobacco of a cigarette except for a cigarette.If it is of any value to you, I have hit a few that satisfy me, and I have forgotten what a burning cigarette tastes like and I don't really have a desire to know.
I kind of look at it like a girl i used to date and is now all hagged out on pills and alcohol. I cant believe I ever went THERE.
But I did for 35 years.
If it helps you, not knowing what you smoked, I smoked USA red 100s cigaretts. They are very harsh.
I have found soilce here;
My Freedom smokes- Pall Mall, Lucky Strike, US light, US red.
Dekang Gold and Silver.
Dekang Turkish.
Dekang Virginia
EC blends 7 leaf tobacco blend.
when trying juice, unless you have someone you can give it away to, buy the small 10 ml bottle on the first taste.
that way if you don't like it you are not out much.
one other thing. I kept my cigs for a week or so when I started. Just couldn't let go right away. Remember , it is an addiction. when I could fight off a cigarette craving with a few drags on the e-cig, I knew I could let go.
I smoked the last one and said goodbye to fifteen bucks a day out the door.
I hope that helps. your'e about to read a hundred replies, so settle in.
Good luck to you.
