How do I know an atty has truly died?

901 atomizers from East Mall....

As long as I've been vaping, I still haven't thrown out a single atomizer. I throw them into a pile, thinking someday I'll get around to cleaning them to minimize my spending habits

So....how can I tell if an atty has truly and completely gone out to the point of unuseable? Example: I have 2 attys I've been using between 2 devices for at least a couple weeks. Out of the blue, one began to produce a dirty taste, no matter how full my cartridge was. The other, just doesn't seem to be working at all. Period. Was working great, then suddenly I'm sucking air.

Are these perfect examples of throw-it-away or can I get some more life out of them? I hate to throw out something that has some life left in it

The best way is to test the atomizers with a multimeter/voltmeter. Perhaps you know someone with such a device.

what should it read to be considered in good use?

You want to test resistance (may be marked Ω) between the electrical contact on the atomiser and the thread. Under 4 ohms is good. A little over 4 ohms is not so good. A much higher reading means it should be discarded. No reading means there is no continuity (and therefore the atomiser is completely dead).
