My coffee isn't as hot as the temperature I set. Is the machine faulty?
Probably not. Coffee brewed at a 190 setting can leave the spout at about 187°F yet read only 158°F in a room-temperature ceramic cup, because the cold mug soaks up heat from the brew. Preheating the cup brings the coffee much closer to the setting. For the hottest result, the top setting is 192°F, which can feel noticeably hotter than an older Keurig 2.
How much maintenance does it need?
Some, and it pays off. Keurig's maintenance reminder alerts you when it is time to descale, and keeping up with it helps both taste and longevity. The pod holder and drip tray lift out easily and need regular cleaning. The housing the pod holder sits in cannot be removed and slowly collects gunk, so now and then it is worth unplugging the machine, cleaning that area with a long narrow brush over the sink, and letting it dry fully before plugging it back in.
Can I move it around or pack it away between uses?
It is better left in place. The K-Elite keeps some water in an internal reservoir by design, so it may leak if picked up and moved, and after sitting unused for a long spell it is worth running a few cleaning flushes before brewing again. For travel, a compact Keurig without an internal reservoir is the better choice.
How do I use the iced setting properly?
Fill the glass with ice, press the Iced button, and the machine brews hot coffee straight over it. It gets the strength right so the drink does not taste watered down, which is the difference from brewing a regular pod over ice, and it works with ordinary K-Cups.
Can I make tea with the hot water button?
Yes. Keurig pitches the hot water button at instant soups and oatmeal, and it is just as useful for an afternoon cup of tea or hot cocoa. The water comes from the same reservoir as the coffee, which is an argument for using the supplied water filter.
Is it worth paying more than the K-Classic costs?
It depends on whether you will use the extras. Compared with a basic single-serve machine, the K-Elite adds adjustable brew temperature, Strong Brew, an Iced button, hot water on demand and five cup sizes. The iced setting and hot water button are the features people come to rely on, and Strong Brew makes a real difference if you like a bolder cup. If you just want a plain cup from a pod, those extras are the whole difference.
