Top Review Praises

These comments reflect the top praises found in the higher rated reviews posted by customers on: Google, Amazon, Walmart.

“I bought this unit for my RV and the feature that works great for an RV is the ability to drain it when the RV is stored especially in cold climates. ”

“Delivers hot coffee consistently. Owned 3 years and descaled once. I owned other units in the past, but the commercial unit is very dependable. ”

“I have had this unit since Christmas 2012 and make 3 to 4 cups a day everyday. Yes it makes a bit of noise, but that is not objectionable to me. I have only cleaned it once in 5 years and have never had the descale light come on.”

Common Review Complaints

These comments reflect common complaints found in the lower rated reviews posted by customers on: Google, Amazon, Walmart.

“Yes it is louder than my other Keurig, but it is a heavy duty machine and in the booklet it says it will be louder because of the heavy duty pump. ”

“I purchased this about 2 years ago and I have to descale every other week. I can descale, get maybe 2-3 cups coffee before I have to do again. Water comes out in slow small stream. ”

“I followed all the directions to the letter. Even in the smallest size, the strongest dark roast tastes weak and watery. It does not allow you to use your own coffee.”

“This brewer sounds like a jet plane landing in your kitchen when it brews each cup! It wakes everyone up in the house. I followed every instruction and wanted to like this brewer for the other great features but the noise is so loud and annoying, we will be replacing it after less than a month of use. “
