I used to use the . I liked them, but Amazon stopped offering them and the third-party vendors want a ridiculous amount of money for them so I switched to these Scotch-Brites, which I find to be just as effective and much more economical.
They fit the hand well, but tend to be a little stiff owing to the thick and durable "scrubby" part. That's a good trade-off though, because they can take on any burnt on mess with just a bit of "elbow grease."
They are as non-scratch as the manufacturer claims. I use them on my Calphalon and Anolon non-stick pots and pans and they cause no damage whatsoever. I also use them on the removable ceramic plates As those plates age, they are losing their non-stick properties but I can still get them clean with these sponges and without damaging the remaining coating.
I see that a number of recent reviews complain about the sponges having a bad smell. I have not experienced this problem. In fact, they have no smell even after using.
