Have been going through high-end Keurigs at a rate of roughly every other year (Yes, I descaled regularly), and I decided to try something different. With my last Keurig showing signs of demise, I thought I'd check out alternatives. Fast forward a few months, and I'm very happy with the Dual Pro. Most of the time it's her having a k-cup, and me having a 1/3 to 1/2 carafe of regular coffee, BUT we've really enjoyed mixing it up with the frother, ice coffees, different fresh grinds, etc. I'm actually "enjoying" coffee again.
Anyway, the Ninja has performed flawlessly, and it keeps it simple, including simple/easy cleaning. Would definitely recommend, especially to someone reluctant to change things up from a simple (& blase') Keurig experience.
