Love the ocello light duty sponges. They are very affordable, and we go through them like crazy. They last a fairly long time, I'm just a little weird and change them out probably more often the regular Susie homemaker. I done let them go to waste though. After the sponge's KP duty is up, they move on the bathroom, window sills, outdoor furniture, floor stains, etc. I think the pretty patterns and colors peak the interest of my kiddos, so they really enjoy doing their chores (oh, how I wish)!
