Example Input: I regularly purchase this item in the bulk and loved it because it was also dairy free. However, my last purchase was disappointing, after opening a brand new package I noticed a black thing in the mix, carefully removed to find out it was a dead flour beetle! I sifted the mix and found more DEAD BUGS!  This is the second time I writing this review. Amazon didn't publish my first review. Thank you AMAZON. I will not be purchasing this item again.

Example Input: Dried mangoes are my hubby's favorite fruit.  He especially LOVES the Philippine brand.  Some come close, but no cigar.  We have searched high & low to find a brand comparative to these, but there are none.  Having them delivered on a regular basis is great & with free shipping.  No more detective work and disappointment.  He does have to be careful however, because he seems to eat them too fast & runs out short of the next delivery, maybe I will increase my quantity!  Quality is the best.  Delivery on a regular basis was a perfect gift for him.  I am very happy & satisfied.

Example Input: Great product.  Recommended by Dr. Oz.  We love pasta but not the calories.  This is much better than whole wheat.
