Keurig K-Duo Gen 2 Coffee Maker vs Keurig K-Duo Coffee Maker

These are the same brewer under two listings: the K-Duo Gen 2, a 72 oz shared reservoir feeding a K-Cup side and a 12-cup glass carafe side. Buy it if you want one machine for a solo pod in the morning and a full pot for guests. The two listings differ mainly in rating history and reported reservoir size, so pick whichever listing matches the model number you want. Owners praise the coffee and the flexibility; the common complaints are the shared reservoir and the glass carafe.

• Choose the Keurig K-Duo Gen 2 (K-Duo Gen 2 listing) if you want the version with the larger, better-established rating base and a confirmed 72 oz removable reservoir.
• Choose the Keurig K-Duo (K-Duo listing) if you want the same brewer in the Moonlight Gray finish option and a listing with a longer review history.
