I just got an MVP 2.0 and am loving it. I also just got a pt2 and kinda like it.. I can build the coils pretty consistently but it seems to be lacking at times. Sometimes it leaks. Sometimes the flavor just isn't there. Sometimes the vapor just isn't there.  Anyways, I was thinking about trying a kayfun but can't justify that kind of money. Has anyone had success with any clones? If so, which ones?  Or am I just not as good at building coils as I think??
