Example Input: I love this time of the year (Autumn/Fall) and love the immense variety of pumpkin food products that are available.  To name a few: Pumpkin Ice Cream, Pumpkin Bread and Muffins, Pumpkin Pie, Pumpkin Spice Latte (coffee), Pumpkin Cheesecake, etc. etc.  I recently started adding canned pumpkin to our Sunday morning pancakes, and was delighted with the results; however, I wanted a stronger pumpkin taste/flavor.  I found this product and excitedly ordered two bottles.  It arrived very quickly (within 3 days), and I just tried it this morning in our pancakes.  The flavor DOES NOT taste like pumpkin whatsoever.  It tastes like a chemical and leaves a bad taste in my mouth, literally.  I dumped both bottles down the sink and had to throw away the pancakes.  I was not able to eat them, they were terrible.  I was actually nauseated after trying to eat them.  I'm not a picky eater and have no allergies whatsoever.  I'm the type of person that will eat nearly everything, and cannot think of any food that I don't like.  I'm going to continue my search for a "NATURAL" TRUE pumpkin extract; however, this is definitely not it.  I hope this helps you, especially if you're as passionate about pumpkin flavor as I am. Happy Holidays to You and Yours.  Sincerely, Tim

Example Input: I was recently put on a gluten & nightshade free diet. Having spent the better part of 40 years eating yummy snacks like cheese & crackers or peanut butter & crackers, I was very unhappy with the new diet. When I discovered that a local grocery store actually carried GF products I was thrilled to find Glutino Crackers.  I managed to eat one. It was nasty. I tried again and again over the next few days to see if my opinion or desperation changed. It didn't. After staring angrily at the box of nasty crackers for over a week I decided they had to go. I took them to work to see if I could hand them off to someone else. Everyone tried a Glutino. Three people actually spit them out and the other two did not come back for more.  I'm not a fan of throwing away food but my husband wouldn't touch them either and there was no way I was going to get another one of these things down. They went in the trash.  Nasty!

Example Input: The tea bags work well with loose tea and buying the pack of six makes this a good value. But what you're not told is that the bags are the large size, better made for large pots and not single cups.
