These are just quitting...as in totally blown when i take my meter to them..I've been dry burning without taking the spike plate off, and that helps sometimes.I used to take apart the ego-t atty's, and the wick would stick to the coil, so I stopped.
The reg. atty's don't have this problem. Are you using ego- c's? I think maybe they're not wicking well enough, thus the intermittent dry hit..
I love the hit when they're working, but don't want to go through 3 per week @ $5. Does cleaning them frequently keep the coil from popping? I don't know.
I wonder if you're popping the coil when you're dry-burning (since you can't really see the coil without taking the spike plate off)?
I honestly don't know why they would be burning out so fast. Here is my suggestion (pretty much what I do): go through a couple of tanks without cleaning or dry burning. Then run it under hot water for 30-60 seconds to rinse it, fill up a small container and soak it in hot water for at least a few minutes. This should prevent the wick from being glued to the coil. Take the spike plate off and have a peek to see if it's gunked. If it is, let it dry first (some folks don't, I do) and then do a dry burn to get the gunk off. I think gunk might be your issue - especially if the wick is sticking to the coil after only 2ml worth of juice.
My only other question is if they're Joye atomizers, or some other brand? There is a huge quality difference in the two, the off-brand ones I got (2.2ohm) weren't worth a lick. I assume since you mentioned $5 a pop, they're Joye brand.
And yes, you can use LR attys on eGo-C systems. They won't last
as long as a regular 2.2ohm atty, and they will cause the battery to need recharging sooner (because you are pulling more amps). But you'll get a better vape, which to me is worth a shorter atomizer/battery life.
Standard Joyetech eGo batterys (3.2V) with a SR atty (2.2ohm) = 4.6 Watts and 1.5 Amps. Not the best vape, IMO. Will not get as much flavor or vapor.
Standard Joyetech eGo batterys (3.2V) with a LR atty (1.8ohm) = 5.7 Watts and 1.7 Amps. Better, not going to blow anything up with that.
Non-Joyetech eGo battery (3.7V) with a LR atty (1.8ohm) = 7.6 Watts and 2.0 Amps. Should be an even better vape, still not going to hurt anything.
