There is no pod coffee maker more beloved than the Keurig line, and none that get better reviews from owners than the Keurig K55. Thousands of happy owners praise its ease of use, the wide variety of coffees, teas and other hot-water-based products that are available, and they adore that it comes in black and red. The K55 boasts a large, 48 ounce reservoir and offers the option of 6, 8 or 12 ounce cup size with the push of a button.
Starts off a bit slow, but then gets brewing. The Keurig K55 gets just a rating of Fair for first cup speed at ConsumerReports.org, but a rating of Excellent for repeat speed. (Note: CR tests the K45, which is identical to the newer K55, just a different model number.) In that same test, the brewer also earns Excellent scores for temperature consistency and Good scores for taste and brewing range. We want to point out, too, that no single-cup brewer in ConsumerReport.org's test gets better than a Good for taste. And owners don't necessarily agree with that average rating. Many say it brews a delicious cup of coffee, quickly and that they love the wide range of coffees, teas and cold beverages that are available. You can also purchase the optional My K-Cup (Est. $15) [B01CU9WU10] to brew from your own grounds.
Intuitive controls. One of the key features that put the Keurig K55 on top with both experts and owners is how simple it is to use. ConsumerReports.org gives it an Excellent rating for convenience. It's very easy to fill, just remove the water reservoir and fill it at the sink. It needs an occasional needle cleaning, -- all pod coffee makers do -- but that's also reported as simple to do. The manufacturer also recommends descaling the K55 every three months for best operation and durability. Descaling is a bit of a pain, but some say it's worth it, especially if the K55 starts to run slow or brew short cups. However, many say they've never descaled their Keurig and it doesn't seem to negatively affect performance.
Generous water reservoir. The water reservoir on the Keurig K55 holds 48 ounces, enough for 6, 8-ounce cups of coffee. It weighs about 12 pounds empty, and has a fairly compact footprint at 9.8 by 14 by 13.5 inches. Users say it's very attractive, with a sleek, modern look that looks nice on the counter. It comes in black and rhubarb. We read very few negative reviews about durability, just some scattered complaints about the K55 failing soon after purchase. Customer service gets mixed reviews, as many users say it's great as say it's terrible, so that's hard to gauge. The K55 comes with a three-year warranty.
ConsumerReports.org tests dozens of coffee makers, including the Keurig K45, which is virtually identical to the K55. Single-serve pod-style coffee makers are rated for first cup and repeat speed, temperature and size consistency, brewing range, taste and convenience. They recommend five models, but none earn "best buy" status.
In nearly 4,400 reviews, which are intermingled with those for the virtually identical K45 coffee maker, the two color options of Keurig K55 earn an overall rating of 4.3 out of 5 stars. All agree that it makes good coffee and it easy to use, but there are scattered durability complaints.
The two virtually identical Keurig coffee makers, the K55 and discontinued K45, earn 4.4 stars out of 5 in around 520 reviews; 90 percent would recommend it to a friend. Owners say it brews a great cup of coffee quickly and easily. Again, there are a few scattered durability complaints.
Although some of the nearly 330 reviews here are culled from the Keurig website, others are unique to Kohls.com. The Keurig K55 gets an overall rating of 4.5 stars out of 5. The red coffee makers earns a ton of love for its attractive appearance, but both colors get kudos for making good coffee and the variety of K-Cups available.
