Got my order! Thank you!!
(Likely a noobie) question: I ordered both Standard (for my passthrough) and Low Resistance (for my eGo) punched cartos. How the heck do I know which is which? I have 5 cartos each, loose in baggies, with no markings that I can tell and they look exactly alike. Can I use them interchangably or will I blow up either my 5v passthrough or my eGo?
