Street King energy drink

Came across these two energy shots today from 50cent. I can take or leave him as a rapper, but business wise he is pretty much genius.
I love energy drinks as much as the next person. I Felt even better about the purchase (3.65 per bottle) when I found out for every bottle sold Street King gives to the United Nations World Food Programme (WFP) to provide one meal for a person who would otherwise go without.

PROS:
•Packaging is sleek & stylish
•Flavors are great (grape/orange mango)
•Sugar Free
•has an average caffeine buzz
•Thumbs up for feeding children

CONS:
• Does not list caffeine content
• a bit on the weak side
