I love the Joker 2.0 and the flavor I got as well. I even mixed a little Dragonade with the Mystery Flavor. I was looking for a bit of a Saints purple theme. This fit it.
The cup is fine. Drinks won't stay cold forever if you're outside in the heat, but it does what it's supposed to do.
The Dubby powder though? That's another story entirely. No jitters. Straight energy and focus for at least half the day, easily.
