I have never tried a mall version of the ecig. My first was the 510 and then onto the eGo. So far, I've converted 4 friends, my daughter's friend and husband, 7 co-workers, and a woman at wally world. My daughter's friend was going to try the Blu cig but I talked her into the 510 instead. So far, she has been very happy with it. You would think that in today's time of computers and internet, people would shop around before buying.
