Query: Not worth it!

Bought one of the reusable filters thinking I'd be able to drink my regular brew... boy was I wrong. Every time I've tried this filter, following all directions to the letter, all I end up with is a weak cup of coffee full of grounds and water all over the counter.Returning this piece of junk today and going to stick with the K-Cups from now on.
