Review on Keurig My K-Cup Reusable Coffee Filter | Compatible with All 2.0 Keurig Machines | 1 Count, Black by Aaron Jones

I bought this because it was supposed to be universal. I just got my first Keurig - K-Mini - and would like to use freshly ground coffee in it. When the package got here I read the instructions, took out the filter and removed the adapter as directed, then tried putting it in the car - and it WILL NOT fit. He was too big. After playing with this thing for a few minutes, I realized what the instructions did NOT say. You have to go under the head of the machine where the coffee comes out and press the nozzle where the coffee comes out - the whole black piece you put the pod in pops out. Then the filter fits in the car.
