I received this filter free from influenster. I have loved having a keurig but found the expense of the k-cups much more than I was used to spending on coffee. This cup has saved me! I had a little trouble figuring out how to get it to work in the keurig to begin but I feel that may have been user error. I did not realize I had to take part of the insert out to fit it in. I love that this filter is easy to take apart and put together and easy to clean. It obviously takes a bit more time to fill it with coffee and clean out each time in comparison to using a k-cup you can throw away but the saved economic and environmental cost is well worth it to me.
