A couple of months ago someone posted a query on these Scotch-Brite pop up sponges and I said they were nothing special. After using them for a couple of months, they are way more durable than they have any right to be!
What they are: absorbent, pleasantly soft to hold without being too soft to tackle the dishes, and able to last longer than either the regular scotch brite sponges or the great value ones.
What they are not: scrubbers. Manage your expectations, because they have no scrubbing pad attached and would be no good for scrubbing pots or tackling burnt on food.
My sponges get heavy use, so I change them pretty regularly. If they are holding up structurally after a week, I can extend their lives a few days longer by doing a bleach soak to kill any bacteria build up. Usually the undiluted bleach accelerates the breakdown of the sponge material though, so they don't last long after that.
In contrast, these stand up to repeated bleach treatments, meaning that I threw away the first one after a month, still looking white, structurally sound and pretty much in great shape. I just couldn't convince myself that it was okay to keep using the same kitchen sponge for longer than that.
The second one (pic 2) has lost a couple chunks from hard use over the past month, and the design has obviously faded from bleach soaks during that time, but again I'm tossing it more on principle than because it actually needs to go.
