Example Input: I have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed.  The tea bag wrapping in question was sealed without a tea bag inside.  I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY.  BEWARE!
Example Output: 1

Example Input: Come on Amazon, give me a break.  Powdered tofu?  Get in some real food and I'll buy more from you. I went looking for table sugar. You've got 100 weird kinds of sugar (that you expect me to buy in bulk!) but NO just plain sugar. I'm not eatin' any more of this rice and tofu bread either.  Sorry I just had to rant.

Example Input: We enjoy our morning coffee and, years ago, bought an espresso machine to stop paying so much money over to Starbucks.  Not only do we like coffee, but we know what we like and this isn't it.  Flat bottom drip coffee makers use a medium grind to brew a perfect cup; while cone filtered drip pots can use a fine grind.  However this coffee is ground, according to the package, extra fine.  This type of grind is typically used in espresso machines, not drip coffee makers.  I have to wonder how much the grind affects the flavor of this coffee.  The flavor is smooth, and non-acidic, while at the same time bland and forgetful.  We usually use a tablespoon of grounds per cup.  We tried the two teaspoons, as recommended on the package, which resulted in a weak cup of coffee.  Using our norm, the coffee had more flavor, but wasn't good.  The only good thing about this coffee is using the used grounds in the garden.  I'm seriously thinking of soaking the remaining grounds so I can toss them in the garden.  If you are looking for a true European coffee, try Lavazza or Illy.  PROS: Used grounds can be used in the garden Not bitter or acidic  CONS: Bland & forgetful flavor
