My-Kap for the Keurig machine

I found this site advertising the kaps to reuse the Keurig cups and am impressed. I thought maybe if any of you read this blog and have a Keurig machine that you may like to try them. Here is the site and I also have it posted on top of my blog. Let me know if you try them. Thanks.http://www.my-kap.com/MYK/
