I’ve used this all in one coffee maker over the past month and have nothing but great things to say about it. First off it is made by De’Longhi, which should tell you about the quality. The user interface is simple, and a perfect cup of coffee (or even a 3oz espresso shot) comes very quickly. I loved the fact that I could use fresh coffee beans of my choice and it is immediately ground when I want a cup. Maintenance of the product is low - and it lets you know when it needs cleaned. Clean up takes less than a minute and is simple. I would recommend this product to both those new and experienced with coffee (including coffee “experts”). We love it and use it daily!
