I have this coffee maker and love it! It gives you a nice variety of sizes, from a single cup to a travel mug to a half or full carafe to choose from, different strength brews, and an espresso-like 4 or 8 ounce concentrated brew. I love the platform to put a single cup on and brew just the one cup, like a Keurig but without the wasteful pod and with the ability to brew the cup the way you like it. The built-in frother is easy to use and works well. The system is a breeze to clean. The main drawbacks are that, unlike a traditional brewer where you can select 4,6,8,10, or 12 cups, your only large pot options are a half or full carafe, it tends to use more coffee than traditional coffee makers, and the heating plate doesn't do a great job of keeping the coffee warm, I microwave the cup if needed. Also, there's no water filter like many units have. I did purchase my unit new and have had no issues with leaking. Once you get the hang of it it's simple to use, no license or special training needed!
