We bought the Duo a little over a year ago. Descaled step by step as they directed. How full the cup gets is Russian Roulette. Sometimes a 12 oz setting gives us 1/2 cup and other times it overflows. A 10 oz setting gives us a perfect 12 oz cup and other times 1/2 tob3/4 cup. Teaching Keurig was not easy, but we persisted. After a half hour+ call going thru a lengthy check, we were basically brushed off with the comment that we were over warranty and it was our problem. Very dissapointing. Guess we will have to look for a replacement from a company that will stand behind their product.

Every time you pour a cup of coffee from the carafe, the coffee drips all over the countertop. This is caused by the small ridge in the spout of the carafe. Take sandpaper with a 220-grit paper and gently sand away the parting line. Alternatively, You can also use a fingernail file.

Nice to have only one pot that does both Works well but I will have to return due to the 2 hour keep warm I need a longer time kept warm In winter I need more hours of hot coffee. In the summer I make the coffee at 3am for me but I have to remake a pot for my husband as he does not wake up till 6am I really wish it could stay warm longer.

Love this machine however the carafe that comes with it is horrible. The carafe leaks horrible!

This product is a win to satisfy all the members of the household.

Really enjoy being able to get 1 cup or up to 12 cups

I love it! Would have given it 5 stars but I think the coffee should be a little bit hotter

Great investment. Instant coffee anytime

The carafe leaks coffee everywhere when pouring

Spill's coffee when you pour it.
