User Review: When we first got this model, the world was different. 911 hadn't happened yet and gold coffee filters seemed like an opulent solution to a non-existent problem. Years dripped slowly by. But then tragedy struck and the first coffee maker died. We decided to replace the unit with an identical model. In the years that followed, we traveled overseas, I was diagnosed with cancer. I got a pet frog. We bought and sold 7 different cars. We lost jobs and got jobs and then changed jobs again. We cried some. We laughed a lot. Our kids learned to drive and ultimately moved out. We paid off the cars. The frog died but I survived. The one constant through it all was a coffee maker that was set to start at the same time everyday (except on weekends.) The coffee maker worked even when I used it. It kept coffee warm if I overslept. We put love notes on it when we couldn't wake up together. It kept coffee flowing when we had friends and family over. It took all we threw at it and when it finally sighed its last breath, we mourned its loss and immediately ordered another one through Amazon. Hard to imagine life without this coffee maker. It looks good and works great. Your life will evolve around it and one day, you'll look back and realize how much the thing has been through with you. Smile and enjoy your coffee.
