This is my second My K-Cup reusable filter.  The first one simply wore out.  I purchased a knock-off reusable filter at a brick and mortar retailer because it was cheaper.  Big Mistake!  Coffee grounds everywhere to the point that I thought my Keurig was broken.  Ordered this one and everything has worked just as it should since.  Easy to use, easy to clean.  I will never buy a non-Keurig reusable filter again.
