Bests & Worsts Reviews from Amazon

I purchased this unit in September from amazon. At first I loved it. Then it developed an incredibly annoying problem where it stopped being able to brew the desired amount of coffee. There was more and more residual water left in the tank. This morning it was unable to empty the tank more than halfway for my travel cup of coffee. I called SharkNinja and spoke with a very difficult to understand customer service representatives. On a positive note, after 30 minutes spent troubleshooting it and attempting to run a clean cycle, they agreed to completely replace the unit with a brand new unit. I then filtered Amazon reviews and discovered that all the one star reviews have a similar issue and were all purchased around the time that I purchased my unit. The ninja representative let me know that apparently a whole lot of machines manufactured at the same time as my unit, have the same problem and they are replacing units completely. I will be happy to update this review and give the product the stars it deserves if the replacement unit performs as expected. It really is a good coffee maker and I’m willing to give it the benefit of the doubt.
