Hey guys...im back and after using my first cartridge for about 2.5 days i do believe it is out of juice. Really amazing considering how much i have been puffing on this thing. I was counting, but lost count somewhere in the 130's. I just popped in a menthol cartridge and there is no difference...still not really any throat hit at all and the slightest taste of menthol....if you really try to taste it. I ordered three 10ml bottles of e juice from freedom2vape...cowboy blend, menthol, and peanut butter. They have a special where $7.99 each when you buy three or more and free 3 day shipping, and they have a location in my state also. Total was $23.99. Was actually wanting to go through DIY Flavor Shack, but they had a 6day processing time due to the holidays, and then 3 day shipping, and i am anxious to get some flavor and T.H in my vapor asap. As to your pic dontwannadie, i really cant answer....i actually used my facebook to register on this site and it combines them both and took the pic from my facebook. Should i clean my atty when i change flavors? Does anybody know? Im still awaiting my 510 also to do a comparison, but will be back to let yall know as soon as it arrives....
