I am having problems with my omega. I thought it might of been the batteries or my atomizer's or cartomizer's but its the omega. I got a new 5 pack of 510 carts and not a single one worked with my omega. Most of my cartomizer's & atomizer's don't even work on it. But the same cartomizer's & atomizer's will work on my 510. It doesn't seem to fire up all of the time. And i have just about had it with all the trashing. I wish now that i would of bought a BSB instead. I am just not as happy with my omega as i was the first couple of weeks. It seems to be more for show (If you don't touch it) than it does for being a dependable PV.
