MizzKitty: I've been having that problem too. I have to vape with the battery held horizontally or bottom up to get consistent hits without the burnt taste. And sometimes I have to hold it with the button pointing up, down, left, right, etc. Don't know why, but it seems a bit temperamental about that stuff. If it gets too wonky, I just refill it because this happens when I don't have a whole lotta juice in it.
