Keurig K-Duo Coffee Maker vs Keurig K-Duo Plus Coffee Maker

Both are Keurig dual brewers that take K-Cup pods on one side and ground coffee in a carafe on the other, so the choice comes down to the carafe and the reservoir. The K-Duo Plus uses a 12-cup thermal carafe that holds heat without a hot plate and lets you move the 60 oz reservoir to the left, right or back, which suits tight counters and people who brew a pot and walk away. The K-Duo Gen 2 uses a glass carafe on a heating plate and a larger 72 oz shared reservoir, and it adds Brew Over Ice; owners rate it around 4.1 out of 5 across thousands of reviews, with the usual complaints about the hot plate scorching the last cups and the glass carafe being fragile.

• Choose the K-Duo Gen 2 if you want the bigger shared reservoir, a glass carafe on a warming plate, and Brew Over Ice for cold drinks.
• Choose the K-Duo Plus if you want a thermal carafe that keeps coffee hot without a hot plate and a reservoir you can place on either side or the back.
