Fresh Wave makes a similar pod with slightly different beads in the packets as well as a gel you can pour in other containers. I have a FW bead pod inside the lid of my trash can on the trash side of a double recycling/trash Simple Human bin. It helps a bit in it, but still not the best.
The gel form factor in containers though works fabulously and I believe is well worth the $$. I got a few small containers at first and then I've been doing the large refill ones.
This other Arm and Hammer Pet Scents deodorizer also works fairly well.
