I was very disappointed after making my first pot of coffee with my new measuring cup. The coffee was very weak. After measuring the new cup with my old cup, I realized it held less. I called the manufacturer at Amazon's recommendation and the person I spoke to measured it herself and told me I was correct in saying the cup was not accurate. She told me she would let the engineers know. The distributor gave me credit. Everyone was prompt in their actions and I was very satisfied with customer service with Amazon, Ace hardware, and the manufacturer.
