It can be hard to see the light, yes red would make more sense than blue, at least on the white ones. And yes, it is slightly longer, bigger around, and heavier. That said, unless you just put down a king (or calibri, I guess, I don't have one) it is still very 'CIG a like'. I've grown to like the tank/atty over a cartimizer, and the PCC that charges an ASSEMBLED unit rather than having to unscrew to charge is a big step forward in ergonomics. My Riva and dual coil mega cartos have been gathering dust since i got the eRoll.
