one of the best chips that you can buy...and i've tried all the kettle varieties, and many others. There's only a slight taste of jalapeno, and they are delicious. Perfect with a sandwich or alone. If you like being addicted, these are the chip for you. ...See you at addicts anonymous...

Ex Output:
Positive

Ex Input:
Hi, coffee doesn't smell or taste great. I recommend Senseo Vienna. Still have packages of "Paris" and nobody wanna drink it. Guess I just have to throw it away.

Ex Output:
Negative

Ex Input:
This stuff will give you a marked energy boost. Note that every person is different. For me, this lasted 3 hours before the crash. (Not a sugar crash.) But my heart was pounding like it wanted to burst through my chest. So I only drink half at a time (like another reviewer) and it works, without the scary heart acceleration. It's even tasty.

Ex Output:
Positive
