This product allows the ease of using a k cup while being able to reuse and choose what kind of coffee you would like to fill your mug with every morning. It paid for its self within two weeks in my home (vs buying regular plastic k cups) and is much better for the environment. Worth every cent in my opinion.
You may need to do some testing on how much coffee you add to the pod, initially)

I was really annoyed when buying the 2.0 and realizing they made it so you have to buy the Keurig specific brand and my other reusable cups wouldn't work. The K cup is 20 dollars for one whereas my other cups were 12 dollars for 4. It does the same thing and taste the same, I actually get grounds in my coffee often using the k cup. Total money grab.

I bought the reusable kcup filter and it was the best $20 I have ever spent. The money I save from buying coffee kcups instead I buy coffee grinds and fill my own kcup with whatever flavor or coffee I feel. What a great investment. I don't think I could go without it now.
