Query: Leaky

I thought this Reusable coffee filter was a great idea to save money by using cheaper coffee, but turns out it doesn't work that well. It leaks everywhere and you can tell the coffee is really light (weak) and grounds are everywhere. I have tried it a couple times and followed the directions to a T. But it still won't work. So sad. They need to improve this great idea.
