My husband & I bought this Keurig Mini Plus in June 2020 to use while traveling (yes, we travel with our own coffee pot!). It's the kind of Keurig they call on-demand, meaning, it doesn't store water -- you add it as you want to make coffee, anywhere from 6oz. to 12oz. Although the exact model isn't made anymore, this is close, for $50 on Amazon:
We used it probably less than 20 times/year, so it's in good shape & very clean. We just need a larger one nowadays. The retractable cord was always getting stuck inside, so we added our own cord winder; it's 12"x12" but very skinny, just over 4". The front part pulls out for storing pods, & the drip tray is removable so that a travel mug will fit.
Note, every once in a while, the Keurig has a brain fart if you do things in the wrong order, & you have unplug the cord & plug it back in to make it work -- kind of like a computer, I guess. It doesn't happen every time, just randomly. Every Keurig I've ever owned does the same thing on occasion.
Please let us know if you have any questions about the coffeemaker. Thanks for looking!
