Query: DO NOT BUY THIS PRODUCT

Bought this product for our office. Worked well for 13 months then stopped working. After having googled this and read many reviews I have realized that this product is very poorly designed. Our coffee maker started by short cupping. Then I attempted to descale it by pouring literally gallons of vinegar through it per the descale instructions. This did nothing to remedy the problem. In fact the computer started to malfunction and pour all of the vinegar/water out without heating it. Descaling did not work. Finally after weeks of trying to fix it I have given up. Of course it is one month past the warranty so I have no recourse. DO NOT BUY THIS PRODUCT. Numerous other consumers have had the same problem. If you see a good review it is usually not related to reliability/durability. It usually starts with..."I've had this product for 2 days and it works great" Fair warning.
