I think I liked a similar drink but this one is just there. It's bubbly. It's sort of orange flavored. It has a sharpness but there's nothing about it that excites me. It's a good old fashioned carbonated beverage and if it's inexpensive buy it. If it's significantly more expensive than most drinks, leave it. Buy coke instead.

Ex Output:

Ex Input:
This bone is nothing more than a big dog treat.  I have a 2 yr old Pit who ate through the souper in 5 minutes.  After reading other reviews I took it away from him and will save the rest for a later date.  I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat.  Will not be buying this again.
