Hi Daveh! Welcome! I am pretty new here also and have had my Vapor King XL kit since last thursday. It's an awesome kit and all the people here have been the greatist help. I also started with the Greensmoke, which if you read the other sections in ECF, it seems we are not alone. When I finally got fed up with it I was one day past the return. They did send me two new batterys to replace the 3 week old ones that had failed. I still liked thier product when it worked, but it's nothing like the Vapor King.
One thought I had with my left over carto's from that unit was using the reverse taryn to collect the juice, and then fill a blank carto with it and vape the juice off your new PV. Yes, it was probably a lot of money compared to just buying some juice but at least you will have gotten something from them.
Enjoy your new kit! Take it from someone who is exactly in the same postion you are, you will soon forget about the old one. V4L is just that good.
