Review (5/5): Cute and fun
Sponges are firmer than the original product like this. They're also smoother and significantly larger. Unlike the original, I find that they don't bleed when washed (with Dr. Bronner's bar soap) and come clean nicely. The silicone spreaders are nice too-- don't peel off the casing, it's a feature not a bug.
I don't know if they work better or worse, but I like them.
To promote drying, I used a regular single hand held hole punch and provide some air holes and drainage holes in the body part of the legs.
