perfect not a thing bad about it!!! 100% would recommend it everyone.

The smell is horrible but the taste is amazing. Very sweet tasting. love that it comes in different flavors. Price is high but worth it to keep me awake

Fellas, if you got a haul ahead of you, go ahead and grab a couple of these white cans. I spend plenty of time running up and down 64 and 95, and this Zero Ultra is my absolute go-to when the highway starts getting long and blurry.The taste is downright good. It’s got a real crisp, clean, citrusy flavor to it, and it ain't syrupy sweet like some of that other junk on the shelf. Plus, you don't get none of that nasty chemical aftertaste you usually get with zero-sugar stuff.Most importantly, it keeps your eyes locked on the blacktop. It gives you that good, steady focus to keep you sharp behind the wheel for hours, and you don't have to worry about crashing hard or getting the jitters forty miles down the road.Only reason I’m knocking off one star is because the price can fluctuate a bit depending on where you buy 'em. But as far as the drink goes? It’s a dang good traveling buddy.
