Works Great!
Other reviewers have indicated that they were disappointed in the durability of this product, but I have not found that to be a problem - mine have lasted through several rinses and wring outs before I felt the need to dispose of them.  I do cut each block into 4 smaller pieces - this provides more working surface area and thus makes them more economical.  Definitely a great little product for multiple cleaning situations - I especially like the fact that they do no harm to my painted walls when I'm removing dirty handprints or scuffs.  I do recommend this product; it's a real time saver!
