Good in general, but not really all that special compared with earlier versions.
I'm a fan of magic erasers, but this was the first time I had tried the extra power ones. I didn't notice a difference other than MAYBE being a little more durable. If it came down to a decision between these and the originals, I'd just go with the originals. With that being said, magic erasers in general work really well. They are micro-abrasive, so they don't show deep scratches like steel wool, but you should still be careful and test them on surfaces you care about before going crazy.
