I had seen these advertised and wasn't overly convinced but now I have used them I love them! When it arrived and I opened the package, one major thing stood out to me: This sponge is the weirdest texture, but in the best possible way. The bristles are super soft, and the sponge itself is wiggly. I'd be lying if I didn't admit that I kept mindlessly playing with it at my desk all day because it felt so cool. It's like a stress ball, but one that you're supposed to wash your dishes with.
Much better than the bacteria hording sponges that I normally use. It's not porous, so it doesn't hold bacteria the same way as a regular kitchen sponge and could easily be disinfected (it's suggested to put it in the dishwasher, but since I am not lucky enough to have one, I planned to disinfect it in boiling water—and wound up having no problems with that technique.
They reach into all nooks and cranny's and for the tough stuff I used the scour pads provided.
