Query: Not satisfied with this product

This product was exactly what I was looking for. You can not purchase one cup coffee makers like this in stores so I was happy to find it on Amazon. Unfortunetly this product stopped working after 3 weeks. It only produces a 1/2 cup of coffee with the remaining water still in the unit. Would like a refund. I would not recommend this product.
