** excerpt: We’ve been testing the Keurig K-Classic for its brew sizes versus K-Cup convenience, and so far, the balance feels just right. The three brew sizes—small, medium, and large—give us the flexibility to customize our cups without sacrificing speed. Our favorite feature is the 48oz removable reservoir; it’s surprisingly large and makes refilling a breeze. The sheer convenience of K-Cups cannot be denied; with our favorite blends always on hand, we save time and effort every morning. While some might argue the K-Classic lacks advanced customization, we’re impressed by how well it marries power and simplicity. If you’re torn between versatility and ease, we think this machine hits a sweet spot without overwhelming you.
