I just received a My K-Cup® Universal Reusable Coffee Filter to replace a previous one we had. The design is silly/foolish. The instructions say to remove the "Pro Series Brewer Adapter" for the machine we have. To use it in that configuration you have to remove the K-Cup Holder Assembly and then each time you want to use a pod you have to reinsert the holder and then remove it when you want to use the Reusable Filter. Sure makes it hard to want to use a Keurig. In fact, the Reusable Filter works fine by leaving on the Adapter. Doesn't anyone at Keurig want to make it easy to use their machines and buy more pods?
