My hub and I love our Ego-T's -- 2 months ago they enabled us to immediately and completely quit analogs, after 45 years of hard core smoking, never dreamed we could quit, never even tried. I also enjoy my 510-T system, lighter, sleeker, auto batteies, no button to push, more 'feminine' in public, sometimes nicer hit. But I very much doubt we would have really quit analogs if we'd started with a cig of the smaller variety. The Ego-T delivers a powerful bunch of vapor, along with a big but pleasantly cool and moist throat hit. Now we like vaping much more than we ever did smoking, there is no throat burn, we stopped coughing immediately. The tanks hold a bundle, the 1000 or 1100 mah batteries last forever. I hate cartos, they have a horrible chemical taste to me. Even the hotter feel of the 510-T's sometimes bothers me. Yes, the Ego-T's leak a little, but it's never a big problem. I just get a bunch of the cheap softer silicone caps, and slap a new one on once or twice a week. We blow out the atty's a couple times a day, I wipe the battery threads once a day with alcohol swabs before charging. We are thrilled, as we knew the real cigs were killing us, not to mention costing us a massive $520 bucks a month, but never thought we could ditch them. One day we woke up and were non-smokers, it was like magic.
I also strongly recommend the low-resistance (LR) Type B atomizers, but I found it difficult to find vendors that would replace the standards in the starter kits with LR's. Two weeks ago we got a second set from MyVaporStore, as at that time it was the only place I could find that would do an LR Type B starter kit. Also chose them because they were on the official Joyetech list. Hope this is helpful.
