The other reviewer isn't the brightest bulb. It's blatantly obvious how to use it, and if you can read it tells you in the description. You use the Keurig to dispense hot water over grinds. The problem is that this thing is the most unnecessary coffee accessory I have ever seen, especially at this price point. Keurigs don't even get hot enough as it is, so you'll have barely hot coffee with this. Just buy a Kalita 155 and use that under your Keurig, or one of the many other great tiny dripper options. You can literally buy a Keurig reusable carafe filter way cheaper, then just cut a hole in a solo cup to set it in and over your cup... and boom, you just saved $30 and still have a stupid item.

The product title is JAVA CONCEPTS REUSABLE POUR-OVER FOR KEURIG. There is no indication in this product that tells you how to use it with keurig. It indicates for regular coffee and tea . MOREOVER, the clear cup in the picture you see is not there.There is cheap plastic cup, different shape that come with it, States "works with any cup). I probably will return it because I bought it for keurig coffee. I don't use it yet. In The product box, it says works with your keurig but the title says pour- over For Keurig. I am confuse, I thought I would not need a keurig machine to use it with keurig coffee.
