Ok so I received my KR808 a few days ago and I love it. I finished off my pack of smokes I had and I've been using it solely for 2 days. The only thing I find off about it is the batteries. When their hot, they're hot, but as they wear down the vapor does as well. It seem the battery starts tapering off several hours before it actually dies. But all in all, I'm highly impressed with the KR808 over the NJoy. I think I will be sticking with this one.
