Im new to external battery mods but have been vaping for 3 years and I know how to prime a coil with e-juice. I go the extra mile after I prime the coil and let it sit for a minute. Then I fill up the tank put it back together and do not touch it for at least an hour or two just to make sure. I just got my now verified as legit sigelei sobra with the moonshot 120 both of the coils from that taste like those knock off BS eBay fake coils. I started off at a very low wattage and I don't know what's wrong both coils are disgusting. It's not exactly a burnt taste or a dry taste it's like a sour off taste and I can't use them. It also makes me feel like I have something in the back of my throat. What in the heck is going on? Do these coils take awhile to become usable? They're the coils that came with the mod and I verified the mod so I assume the coils are also okay. I even went so far as to try the second coil on a different mod but with the same tank just in case the mod was frying things the very first hit. Can anyone give me an idea of what's going on so I know what I need to do and also if anyone could tell me whether or not the Cascade baby coils will fit in the moonshot 120
