I don't understand why people like/praise these things so much? They're just a gimmick to me.
I smoked hand rolled for 37+ years and my wife smoked for almost as long. E-cigs have allowed us both to quit tobacco completely for almost six months now. We both feel much better. Food tastes better. We can smell things again. Neither we or our home smell like an ashtray any more. I don't wheeze when I lay down at night any more. My wife has been able to halve her asthma medication. A gimmick? No. Real, genuine, life changing? YES.
The throat hit hurts; its nothing like a real cigarette hit, it has an awful taste < i have like 7 different flavors>
If it hurts then you either have too high a strength of nicotine or you are susceptible to PG based liquids. VG based, or a higher percentage of VG will give you less throat hit and a smoother feel. Awful taste? then you haven't found the tastes that you like. I have more than fifty flavours in my drawer and it took me weeks to find the ones I like. Now I have I love them far more than I ever loved inhaling tobacco smoke.
The absolute pain of refilling these stupid things is enough to make me never want to quit smoking.
Everyone is different. Some love dripping. Personally it would drive me bat.... insane to have to top up every three or four drags. Some love carts like the Ego. Again constantly topping them up or burning the filler gives me a major pain in the neck. I now use XL clearomizers that hold 1.8ml. I top up maybe twice a day at most. Compared to the amount of time I used to spend rolling cigs that is nothing.
Only you can decide that. Maybe you are not ready to quit yet, or maybe you expect to find an off the shelf works every time solution in ecigs and they just aren't that advanced yet.
But I, and thousands of others around the world, are convinced these things can make the difference... they can get you off tobacco and still allow you the pleasure of the smoking act. But you will need to put your mind to it and persevere, and keep trying different systems and different liquids and different nicotine levels and different PG / VG mixes until you find the set up that lights up your bulb.
The alternative is to go back to smoking and kill yourself much sooner than you need to.
I really, really wish ecigs had been around 30 years ago.
Good luck in what ever you decide.
