I received one of these when I bought my Keurig at Costco a few years back - and I use it every day. I rarely purchase the disposable K Cups. We always brew ground coffee in this reusable pod. Love it!

This is a fantastic addition to any Keurig! This way, you can still brew your single cup, PLUS, save a ton of money by not buying the individual k-cups of coffee! This is used all the time in our house & I'm so glad we're also not filling up the garbage up with a bunch of plastic cups!

I love this piece of equipment but I love it for loose tea!

Although I bought this so that I could use it for specialty coffees, I bought another one for the speciality teas. I also find that if you soak it in CLR, you can clean it, so that the little filter holes unplug for the tea leaves and you will have it forever. I've had one of mine for 5 years.

Available pretty well wherever they sell Keurigs, this adaptor allows you to use regularly ground coffee in your Keurig machine. I just replaced mine after 3 years, and have saved a lot of money as a result. My son tells me there is an even better one on the market, which I am looking for. I love my Keurig, but it is an expensive luxury.
