-Extra accuracy in temp, perfect for finding different vapor levels.
-Digital read out is great to know exactly what temp I'm at and great for vaping in the dark.
-Auto shut off has come in useful many times when I've left it on.
-My friend owns the Classic and mine seems quieter which is nice but not a major decision factor.
-In a radio interview Storz & Bickel did with the Dopefiend (show was dedicated to a Volcano Digit review ) they said there are other upgrades but they can't talk about all because they are scientific and relate to patented technology issues which is understandable .
-Overall performance is pretty identical to the Classic.
I say if you have extra coin and wan what you pay for, get the digit. Best "paraphernalia" I ever purchased .:thumbsup:
