The fancy Bookoo logo, in blue/purple on black. A nice color combo and great graphic design. Added "Zero Carb", which does a fine job of informing you that this beverage has no carbs.
Bookoo Wild Berry Sugar Free has a pleasant, refreshing flavor. A nice deviation from the standard Monster Lo-Carb knockoffs. It had a little too much raspberry flavor for my taste, but a nice blend of tart flavors still made it an enjoyable energy beverage for me.
Bookoo Wild Berry Sugar Free also contains an acceptable blend of energizing ingredients. Like its miniature cousin Bookoo Wild Berry Energy Shot, this performed more on flavor than energy, but not to say that the energy content is disappointing, just the flavor is far more impressive.
The Bookoo line is exceptional for flavor. They make almost every other company (Jones's being the one exception) look like they are rank amateurs. The energy could stand to be slightly more intense, but overall, still an ok value at $2 each. Because my two main criterion are price and energy, taste takes back seat. I think this is the three-way tug-of-war that everyone considers when buying an energy drink. This is a good drink for people who lean more toward taste, and are on a lo-carb diet. For the health-conscious, you may want to note the 200mg of sodium.
Let me start by saying that it's no Diet Rockstar as far as lo-carb energy drinks go. It also made me feel a little sick, but this may have also been caused by drinking it on an empty stomach, around 1PM, while reading home loan papers.
The taste is good, but clearly diet, the regular version of this, and the energy shot are so much better tasting. It is a nice change of pace from the other diet energy drinks. Bookoo makes great beverages, but their diet versions are particularly to my taste.
The energy is good for a sugar free (since 220 calories/can help add to the energy boost of most regular energy drinks).
Cases of Bookoo 16oz. are available on the Bookoo website for $25/12 case. This works out to almost exactly $2/can, with free shipping. About what you're probably paying for something at your local gas station, so I'd call it an average price.
