A few days ago- I went to this new e cig store. I bought a Joy Tech Ego Cig. It is a pass through with a 1000 mah battery. I have been wanting an Ego cig for a long time- because I have heard so many great things about it. I am concerned with the authenticity of it for a couple of reasons. It does have a logo on the bottom that says Ego-C and it came in a Joy Tech box, but the logo is a little different from the ones that I keep seeing on the internet. I have also read that my Ego cig is suppose to have variable voltage. These sites on the internet say that if you hold the button down for 5 seconds- the light will turn orange and I will be able to smoke at a higher voltage- but nothing happens when I do this to mine. I also bought 2 mt3s atomizers from this same store and the first one leaked out all over me the very first time I used it and the second one kind of works- maybe for 20 puffs and then it gurgles, fills my mouth and my tank up with liquid. I have spend over $120.00 in the past three days trying to get this thing to work right- and then I find out it's not even doing what it's suppose to. Are all pass through ego cigs with a 1000 mah battery supposed to have a variable voltage or did I get ripped off?
