Save your Keurig coffee maker with this product!
We have exceptionally hard water.  I went through two Keurig coffee makers before finding these little de-scalers.  The scale build up was so bad, the vinegar rinse wouldn't work.  I now keep one of these in the water storage container of my kuerig coffee maker and can visibly see the difference - no more hard water lines.  I'm thinking about placing one of these in the toilet tank as well to prevent the hard water stain in the toilet bowl.  I will let you know if it works!
