Smooth Criminal has a mild and unassuming flavor with a hint of sweet. It's been a great all day vape and is what I've preferred for nearly half a year now.
The flavor can be described as a mellower and simpler version of Boba's Bounty. In some atomizers it has a smooth and rounded character that has hints of tapioca; in airy atomizers like the Aspire Nautilus Mini's it has a less round character and flavor reminiscent of hay.
I wasn't immediately attracted to the taste but it is definitely a juice that does not fatigue. Unlike other juices with stronger and more distinctive flavor profiles, Smooth Criminal subtlety pays off by never over loading your tongue or teeth with sweetness nor does it overpower with any distinctive flavor.
The vapor production is very good although it tends to vaporize more quickly than other juices I've used.
I've only bought the premixed XPress version which I think is 50/50 pg/vg
Works well with Vivi Nova, Aspire BDC (ETS coil), Joyetech eGrip
Sucks with Kanger Protank, Aspire Nautilus Mini
