Ok, so I emailed myvaporstore.com (I bought the kangers from them) to let them know that I was getting a burned plastic taste. They asked me my battery type and the voltage I was vaping. I let them know that I was using an AW IC battery at 5 volts. This was the response I received:
So, I guess that means you can't use these things with VV devices. Bummer, wish I'd known that before I ordered ten of them. If anyone is interested in trying these out, let me know, I have 8 of them to get rid of now
I will say that I am pleased that myvaporstore had such a quick response to my emails.
I'll gladly take the 8 leftovers off your hands for $1 each!
