My brother actually has a Keurig. I have no idea how good the coffee it makes actually is. The only pods I've used in it are for green tea, which anything capable of heating water could make.
It's Starbucks-grade coffee. If you actually like coffee, you won't like Keurig. It's value is in how quick and easy it is to use it.
As someone that does not drink Coffee, I was under the impression that Starbucks is considered good/above average.
