To get a more intense taste, I mix two packets in a 16-oz BPA-free Camelbak bottle, adding 8 oz of water and the rest ice, plus a packet of Stevia, shake well, sip, and oh so good! No-calorie sweet tea, green tea antioxidants, and I'm drinking a lot more water. I also carry packets in my purse and add to water in restaurants, saving tons of money from ordering drinks and not to mention calories. Although the Stash rep tells me there is a "negligible" amount of caffeine, the placebo effect gives me a great boost in the morning before my workout. Since I love mint, I think I've found the perfect product.

Ex Output:
Positive


Ex Input:
Great selection of chips & very fresh. If you are are looking for a healthy alternative to fried potato chips & don't like the fake taste of baked, these are just the most amazing chips you can eat. I bought 2 cases & every time I'm at Target or our Super Box Store I make sure to pick them up!!

Ex Output:
Positive


Ex Input:
I was very disappointed when this toy broke in less than a week. It was advertised as being durable plastic, but it couldn't stand up to our beagle dropping it repeatedly to get the treats out. The plastic lid on the bottom cracked and broke off less than a week after our dog began playing with the toy. The broken plastic pieces are very sharp and would have been dangerous if our dog had not been supervised.

Ex Output:

Negative
