This is my original post about my Prodigy and atomizer failures.
I have yet to discover how to keep my Prodigy from blowing up my 510 attys. The first 2 older attys I tried on it were fried on the first hit. Last night I lost the new atty that came with the Prodigy in only 6 days of use.
Since April I have been using the 510 and had only 1 atomizer die a mechanical death. I've had 4 die from being clogged with carbon. They still mechanically work they just no longer wick juice from the cart. I don't know what the solution is but I can't keep losing attys.

Thought I would update my original post on this subject, since it's been almost a month now on my Prodigy. My atomizer problem appears to be not the fault of the Prodigy at all. After those first issues I had originally blamed the failures on the 5 volt Prodigy, but since those original problems I have had no further issues.
This past weekend I tried to revive some poorly performing atomizers. After trying them all on 3.7 volts and not being satisfied with the results I decided to try them at 5 volts. I said if they blow, then they blow. But to my surprise not a single one of the 5 old atomizers were damaged at 5 volts. All of these atomizers had 3.0 ohms resistance. So there went my original theory right out the window. It wasn't the higher voltage alone causing the atomizers to fail.
The only conclusion I can come up with is at 5 volts a weak or bad atomizer will fail quicker. I've even tried vaping at 6 volts and have had no issues other than a bad taste.
So in my experience so far it is important to check the resistance of your atomizers. The resistance should be normally around 2 to 3 ohms. This will give you an idea of the electrical health of the atomizer. It will not tell you that there is or isn't a dirty coil. An atomizer coil that is coated with carbon will still have good electrical resistnace.
There are 3 types of atomizer failure:
1.
Electrical problems that can be detected with an ohm meter. Resistance higher than 2 to 4 ohms is not normal. This indicates something is breaking down either in the coil itself or the coil connections are going bad. Be sure that the multimeter you are using can be trusted to give fairly acurate numbers.
2.
Coil coated with carbon. This is hard to correct due to the toughness of carbon. It is extremely difficult to get rid of carbon build-up. Some try dry burn, hydrogen peroxide burn and other different ways to clean this carbon off. This is the leading cause of atomizer failure.
3.
Wicking problems due to juice clogs. This problem is usually easy to correct by soaking in alcohol or other "safe" solvents.
It is my theory that atomizers with a higher than normal resistance will fail at higher voltages. This is due to heat from the voltage drop accross the problem that is causing the resistance. Right now I can't prove this.
I hope this helps someone.
