Very practical for everyday cleaning after a walk. Personally, I use water with a little apple cider vinegar that has antimicrobial action and my dog's paws are always clean.

It seemed like a good and practical idea to buy it, but it has problematic to non-existent usage instructions. I don't know what to put inside and in what quantity, and if simply dipping the dog's paw and passing it through the sponges, maybe even wiping afterwards with a cloth, is okay. I haven't used it yet for this reason.
