Hi all, I have been vaping for a few years now and have used only the 901 so far but I'm starting to get annoyed with the weak atomizers. I am a chain puffer just like I was a chain smoker. On the good side I have quit a 30 year 3 pack a day cigarette habit. It's been over a year and I am sure I will never pick up another cig which is awesome in itself. I initially chose the 901 cause it was the closest looking thing to my cigs. I buy juice and add to blank carts. It just seems it's hit or miss with the atomizers being weak. I have always been a deep inhaler so when they are weak I just order more but now I'm really considering trying something else just don't know what to try. I am at home most of the time so I don't have a problem with charging often. I would just like a heavy vapor, if you know what I mean. Any suggestions would be greatly appreciated. Thx again, Steph
