I was excited to use this for my ground coffee, but either I am doing something incredibly wrong, or this product is no high quality. Coffee goes into my tall mug, but, alas, hot water leaks all over the place.I would not recommend this item. The surprising thing is that I have a Keurig pot that is specifically listed to be compatible with this Keurig-brand K-cup reusable filter. Really makes me wonder if they actually tried it on their own pot.
