Ex Input:
Good quality nectar.  Very tasty.  However, I was expecting 46 fluid ounces, not 46 ounces in weight.  I find that 46 ounces in weight makes about 32 fluid ounces.

Overall, the bags of popcorn were just like those that you'd get in a regular package of 8 or 12 bags.  However, several bags did not pop correctly (or at all) and had to be thrown out.  Also, many other bags would have a burnt hole after popping.  I realize that some of this variability could be due to microwave wattage, but it was only bags from this large box of Orville Redenbacher's that would do this.  I think when you order such a large box, your chances of getting "dud" bags increase...just something to keep in mind!  Is it worth it to buy in bulk when more of the bags will be duds?

Ex Output:

I actually was delighted to find this product, and my family and I loved the recipes made with it.  However it has sugar as the 2nd ingredient AND worse it has aluminum in it.  Why would I intentionally feed my family something neuro-toxic when I am trying to avoid gluten to keep healthy?  I sure wish those companies who jump on the GF bandwagon would keep health in the equation.  My kids bowel movements are gluten free too, but I wouldn't serve it to them for breakfast.  Just sayin...
