So far I have owned my eGo one for about 3 weeks, I am so happy with this. I got the XL Version and it has so far been perfect, everything and more I have wanted in a e cig. I am probably more impressed with it since all I have owned previously was a bunch of cheap ebay crap. The 1.0 coil gives a nice hit, I really dig the vapor production I have been getting, the 0.5 coil pulls a real huge hit, sometimes I feel it is even to much, but great for a bar night when you want a little more of a hit. I have used thicker juices with it like Modzilla and I have used some thiner juices with it like some of halos juice line. The eGo one can deal with it all so far. Never had a leak, and never have burnt a e juice. It is all I use all day and every day. Been using it a good 12-15 hours a day always vapping on it.
The only thing I did notice was the battery has changed since the first week I have used it. It use to last all day without out needing a charge, now 3 weeks in it does seem to die at in the evening, I just purchased a second battery to have one on standby. Like I said though I do use it all day. So far I love it, Joyetech personally hit a home run with this e cig.
My current set up with it is the glass drip tip with the 1.0 coil and airflow wide open in use.
Real easy to clean to, just dig it all around.
