I have a dse 901 and I am wondering why my vapor is cool instead of hot. I am using VG as my base with VG based e-liquid. I have tried just flue cured flavor with VG and also flue cured,VG and menthol crystal liquid. It is less cool without menthol, but cool non the less. Really cool with menthol added. I am getting lots of vapor production. I was just wondering if this is normal or do I need to try a different model to get a warmer vapor?
