I have previously owned larger Keurig. I was excited to receive this free product for my unbiased review. I love the size of the K15, its small so I can easily fit it into corner on my countertop. I also love that you only put in the amount of water you will use. The visual cues are a big help so using the machine is easy. My only gripe is that I cannot fill my travel mug because of the small size. I normally make a cup of coffee in the morning to go and a cup of tea at night. Other than that, I am pleased.
