Query: Saves money

These work well with my older Keurig model. Be sure not to overfill them or some grounds will leak out and get in your coffee. I measure 1 tablespoon of medium grounds (not fine) and it works fine. I prefer a certain brand of coffee that is rather expensive in pod form, so using these will save a lot of money over time. There are enough to bring a few to work as well for our workroom machine.
