Early preorder for a blue ff got the email and went ahead and changed to black. Like @darkrom said it's only 30 for a different color top if I decide I want one down the road.
@Vital i use my wife's blow dryer to dry after I clean it. Take the most water out of it and then dry the remainder of the tube with the blow dryer. The only thing that really has to be dry is the connection you sit it on top of the Evo.
The turbine is a bit better in air flow not by a lot but the flavor is the main difference. The diffusion is great, my face melts after every hit though because it's so smooth by the time you feel it in your lungs it's too late.
I just sent my mighty back because of it only issue which is the batteries running out of juice and not being able to replace on your own. Other than that it's probably my second favorite after the grasshopper.
