Hey all, I just got an IATTY from another EFC member and It was never used before yesterday when I got it. It is awsome!!! It gives out Hugh Clouds, Like I have never seen before, But It just seems like a bit of a hastle... I have watched a ton of videos and read a ton of reviews and this thing is everything people say it it. I am very TECH inclined but I think, I personally, might be better served with the UFS! I have never used a UFS, they seem a little easier, or faster to start using. I dont mind doing adjustments or fiddling... Can anyone who has used both please let me know of your experiance with both of these tank systems and which one you feel is easier or better. Thank you and Happy vaping From a proud GG Owner..........
