So, I got an EHPRO Valkyrie clone a few weeks back and was enjoying using it with a .8-.9 ohm dual coil. Great flavor, good vapor production, etc. Then, one day, I noticed that the vape was not up to par. It was like not enough power getting to the coils. At first, I thought the battery was dying and tried another fully charged. Same thing. I looked at the coils and they would slowly heat up, but only glowed a dull red. I had to push the switch very hard to get them to do even that. I took the switch apart, cleaned it, put it back together. Put in some new coils. Same thing happened. Now I'm noticing that the switch is warming up when I use it. Here's my question: What the heck is going on here?
