It's a low cost keeper

I like the taste of fresh brewed coffee so I'm a fan of single serve makers for use with generic, refillable pods. My Instant Solo died this morning and I didn't have a backup. I prefer a maker with a reservoir but this is a keeper as my backup so I'm never caught without again. It's no frills but easy to see inside to determine how much water is needed for each size. Choices are capsule or ground and it works with my generic refillable pods.

Coolest little coffee maker.

OMG, I Love this. Yesterday my Keurig died. it was the original model that I've had for years. anyways, this new Mainstay is awesome. as soon as I set it up %26 made my first two cups. I gave my Keurig a funeral of respect and put my old "Mr Coffee" coffee maker in storage.i now have so much open space on my counter that I now have the room to put my new steam grill my dad had also bought from Walmart to use. I love that too. Thank you Walmart and thank you Mainstay.

Love my mainstays single serve k

I love my mainstay single serve k cup machine. Fits nicely next to my 5 cup coffee maker. So simple to use because it lets me decide how much water to use per cup. It gives me their ability to use the pre-filled K cups or my own coffee grounds, which I love to do. I get fresh hot coffee every use within literally seconds start button. I would highly recommend this machine to anyone just wanting a K cup coffee maker that may be in a tight budget and can't afford the expensive machines and up. Definitely great for anyone that doesn't want a lot of buttons to fiddle with also. This would make a great gift for anyone looking for a simple coffee machine, I highly recommend it. Thank you, Walmart mainstays for giving us this coffee maker. Have a great day everyone ☕️☺️🥰
