I am some what new to vaporing ....I am using a Kanger Tech Mini ProTank 3 that uses the dual coils 1.8, seems every other boxes of 5 I buy from my local vape shop has at least 1 bad coil in it.....the first time I took it back to my local shop but they made statement to me that they usually don't exchange another one for a bad one, this last box I brought last week has another bad coil in it....is there any recourse I can do though Kanger Tech to get back my money or working coils exchanges.
It's just a "to-be-expected" thing that in every batch of 5 there's going to be at least 1 wonky head. I've had boxes of 5 where 2 or 3 behave weird. It'll make you think it's something with your tank but nope, it's just the head. They're kinda shoddily mass-produced (their failure rate, as you can experience, is
really high.) It definitely sucks, but it's something many vapers eventually move away from as they get into rebuilding/relying on their own failure rates rather than the sketchy China factories that pump out these heads.
I agree with
@Larry J, the new Subtank OCC/VOCC heads seem to be a LOT better, primarily because of the cotton wicking. By default they come with .5 ohm heads, but you
can get 1.2 ohm heads. Just make sure you have a device that can supply ample power to that kind of coil before you pull the trigger on a Subtank Nano (I'd assume you'd prefer that size, given your current ProTank Mini).
