This sponge works much better than the sponge that comes with the Butterfly Spin Refresh. The only problem I had with this sponge is that if you keep it outside the plastic sleeve that comes with it, it dries out and becomes a hard piece that needs soaking in water for some time.

I bought one of these a couple of years ago. It dries hard if you keep it outside the provided plastic bag. But if you keep it inside the plastic bag this sponge is much better than the sponge that butterfly makes. This cleans the rubber much better.
