So since i bought my first LR atomizer, i subsequently quit hv devices, I have tried and lr 801,510,901 and now finally got to the 306 from clouds of vapor. and I dont think there is any going back, Unfortunately i dont have a drip tip, and i do not know if there is a break in period, but on my icon with aw bat's this thing is a machine. at one 1.8 ohms out of the line it is clearly a winner. its a more flavor than 510, and so far coming in at a close 2nd to vapor production. it makes my Backwoods brew taste even better than it already did, and that is no easy accomplishment... bottom line is if you dont have one, get 10.
