It's way to big for my daughter who's a toddler. I tried using it once and I find it to be very uncomfortable...I'm comparing it to a Brookstone travel pillow.

Ex Input:
This was an "Amazon Choice" item. I ordered July 4, 2019. Latest delivery date was Aug. 15th. I waited a week and still didn't receive it. Amazon message says it's not covered by A to Z guarantee. Now waiting for reply from vendor. Low satisfaction on ratings. Spend a couple bucks more and get it delivered.

Ex Output:

Ex Input:
I found this has the most satisfying and authentic taste for use in cooking, and the price makes it good for saving against the purchase of many smaller containers if you use it enough. If you don't use it that much, you're better off forking out more per ounce on a smaller size.
