So strong, you can use (and rinse) them as a sponge to clean your whole kitchen while avoiding the negatives of an actual sponge.
The select-a-size allows for a more reasonably (half)sized default selection, though I often tear even that in half for whatever it is that I need. I've actually seen some people saw the whole roll in half and that seems pretty appealing to me. You could still leave them stacked together on the dispenser, but I wouldn't have to leave half of a paper towel just floating nearby.
(Thankfully they've finally helped people price compare by having their different roll sizes actually make sense: single, double, and triples. It used to be ridiculous with "super" (1.83 regular rolls) and then "mega" sometimes being 12 = 20reg or 12 = 26reg)
For other sponge/paper towel alternatives, I would recommend looking into what the europeans use — my brother-in-law has a different favorite for every type of cleaning.
They carry them at The Container Store
And there are tons on Amazon, branded as "Swedish Dishcloths" (with some pretty cute prints available).
