I just got my first 901(Ruyan Direct) in this past tuesday. I love the amount of vapor it produces and how easy it is to top off, however it is tending to get a funny taste. At first it had the usual strange new taste that most new attys have and go away after a day or so, but, the taste I am getting now is a kinda burnt nasty taste that keeps coming back shortly after I top up 
Any comments would be appreciated?
