I also love these replacement cartridges. They work perfectly with the litter genie and are a much better deal. I've never had one break and the odor control is great. They are 21' long as opposed to the name brand which are 14' long and they are cheaper than the name brand. This is a great product and I strongly recommend it to the more expensive alternative.

I was purchasing these on Amazon, but they stopped being available there. The shipping from this site was free and I bought two sets of 4.
