Customer Rating: 



Summary: Just what I expected!
Comment: This product is great for brewing your own coffee grounds! Though the little K-Cups are great for the quick cup of coffee, buying this reusable filter helps keep the costs down as you can put your own grounds in. Daily routine: Get up, grind coffee (separate grinder), put grounds in filter and brew. Easy to interchange with K-Cup adapter that the Keurig comes with.

Summary: Where is my coffee!!
Comment: Not quite happy with this thing.. Initially I thought the ground is not the right kind, but it is the same with different grinds I have tried.
What you get is a
1. Mess
2. Weak coffee.
3. which gets luke warm by the time U are ready to enjoy it.
Stay clear of this product.
Yet with so may encouraging reviews.. I am still sure I may be doing something wrong...

Summary: Perfect!
Comment: This was an excellent purchase. The product was shipped to me way much earlier than I expected -- it came as a surprise! I am very happy about this purchase and I highly recommend this seller. Thanks a lot and more power!

Summary: Hard to get in & out of machine!
Comment: Was very excited to get this Keurig accessory and brew own coffee. Unfortunately, it's rather tricky to get this filter in and out of my Keurig machine. Very tight fit, and worried about breaking something! It's not nearly as wonderfully intuitive a product as the Keurig itself. Very disappointing.

Summary: Good route for inexpensive coffee on the Keurig
Comment: Good way to use your own brew in the Keurig. I bought it at the same time as my Keurig coffee machine, and honestly have not used it much due to the overwhelming variety of coffees, teas, and even hot chocolate available for the Keurig in pre-made brew cups. But when I do use it, it works well (and using your own coffee is less expensive than the ready-made cups).
