I decided recently that I'd quit smoking and that I wanted to give e cigs a try, so I went and got an ecto 1100 with a bottom dual coil tank. I used it for a few weeks, and when I went to the store to get new coils I spotted what ended up being an aspire nautilus. The shop guy said that the nautilus was one of the better tanks they had for the price (35) and that he personally uses one and highly recommended it. After giving it some thought I ended up going back to the store the other day and picked one up. I did some research on them before hand and I told the guy I was worried I might have bought a clone and he laughed and said I could scratch the code on the back and put it into the website on his computer and if it turned up used or fake he would refund my money, luckily it was legit and after getting it home and filling it up and letting it soak, my mind was blown away, my personal experience was much better than watching YouTube videos on the thing. I had no clue this much vapor could be created! Yesterday I went out to get a few more coils for the future and the guy who originally recommended the tank to me was there and asked how it worked and I told him I couldn't be more pleased, then he conned me into buying an ego c twist 1000. Got home and charged it up, played with it until I found my favorite settings and now I see why he talked me into getting this thing. On 3.6 - 4.0 using the 3rd and 4th hole on the tank, I think I am in love. So there you have it folks pack a day smoker to vaping. Going on a little over a month now and not missing a thing about cigarettes.
