I think that Fedor tried using his 801 batteries, and found that they would not fit/work. That being said, i get more flavor/vapor than my 901/401/510, . I have also been using the same atomizers since March, so they're very robust. Its also nice to see that you have them in black, as AEC only sells them in white. Your pricing is also VERY competitive.
Just a quick question, what color are the leds?
