Does the tank work if you try it on another mod?I usually only run the AL85 at 45 watts. It holds up white well with the stock tanks/coils for the kit. It's just this V2 tank that's giving me problems. It worked for a few hours last night, but is back to not working again this morning with a freshly charged battery. I purchased the Samsung batteries from electric tobacconist.
As for smok stuff not lasting....I've had this AL85 kit for almost 3 years now.
