I am new around here but I started vapeing with a 510 MEGA. After reading here on the forum about other models I picked up a Elegant Easy. The Easy has a much larger battery as you all know, I am a truck driver and as such you just cant pull over anywhere and park, I thought the extra battery life of the Easy and the cartos would up my vapeing experance as well as cut down on the work. The Easy worked ok, but I just didnt get as strong of vaper out of it. I just wasent full filled as I was with the 510!. Sometimes the simple and inexpencive things in life turn out to be the best!. I am only sorry I spent as much money as I did on the Easy, used it 3 days then put it away for my trusty MEGA.
