I just received my evic today and this is my first APV but i must say this thing is very cool with all the features and all the information it displays on the screen. Before i figured out to display the ohms and volts on the screen i was going blindly at setting the watts. Alot of burnt taste but once i got the ohms and volts on the screen this thing is a dream. I have nothing to compare it to since all i have ever used are ego twists, i never tried a provari or a zmax or a vamo etc etc. Just wanted to say i am very satisfied with my purchase : D and happy to join the evic community, who needs a provari anyway :/ .... jk lol
