This Keurig is the greatest thing I have ever gotten. It is the perfect size for my small apartment kitchen and is super easy to use. I share an apartment with my significant other so it always seemed like a waste to brew a small pot of coffee for only two people, but the Keurig solved that. We just both make a single cup of coffee for ourselves and we're set. Even when I wake up late in the morning, I can put in a K-Cup and by the time I'm dressed, I can grab my coffee and be on my way. The one thing that I wish the K15 had was an external water indicator so I could see how much water is in the machine before I brew a cup. I'm just afraid that I will put in too much water and the cup will overflow. But even in the off chance that it does overflow, the K15 has a drip tray for exactly that problem!
