I just received a couple of Giantomizers from COV this morning and I must say that after reading some of the comments in the reviews section I didn't expect much. So far, after four hours of use, I am extremely happy. Lots of vapor, clean taste and no leaks at all so far. Opened up the package, filled with 3 ml of 50/50 Menthol Artic, placed a drop of juice on the coil to prime, replaced the mouthpiece and vaped away. The only thing I've had to do since I started was pull the mouthpiece and blow out the condensation after I chain vaped a few times. I am not new to this even with my lack of posts. I was a two pack a day smoker who quit on 3/12/10 when I bought an 801 pennstyle ecig. Soon switched to an ego/riva and have mostly used mega carts with blue foam mated with cylinder atomizers. I've tried mega ego cartos, ce2's(all styles) and this is the best out of the box experience I've had. Just hope I can say that next week.
