Ok, on Bum Energy :
Pros : The taste is fucking awesome. I have used 6 of the 12 I bought and this is the ranking so far :
Root Beer
Grape
Blue Lemonade
Hard To Kill
Pink Lemonade
Cola - tastes like a diet cola
Cons : only 112mg caffeine per can. Which is low for some people, but for someone using 1/3 of a Bang per day, it is perfect for me.
Would I purchase again? Yes. If it was the $1 sale. No, it was the $2.99 price.
