I actually just had to get rid of mine the 510 pin fell in in the rubber seal fell off. I used the Flight 510 adapter since I've had it only took it off twice one day it just stop firing. I just ordered the kamry 20 Watt box so we'll see how that goes. I think they might have made it a little bit better than the 30 but I loved it it was one of the best
mods I own ,specially for That price I may have to order a new one soon, Just letting people know to be careful with it don't screw it down too far if the threads are very long
