Ex Input:
these chips are good, and bad, and create moral dilemmas constantly. If wou are strong at will, or having a large BBQ go for it, but as for me, i was in the habit of bringing a new bag to work every three days, had to put in a lot of time on the treadmill to make up for it. BEWARE

Ex Input:
I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!

Ex Input:
These bites are 'just enough' for a snack. They are delicious and the price is very reasonable! I will definitely purchase from this company again.
