Product review (3 stars): Some parts are great, others not so much
These sponges are great in a way because they do not get smelly sitting on the sink between uses, unlike fabric sponges and scrubbers. They do a pretty good job of basically squeegeeing off dirt and food residues. However, certain kinds of debris can accumulate in the holes of the cleaner.  Further, the inability of these cleaners to hold any water (as one is used to when using sponges and similar cleaners) is strange and you need to change your approach to cleaning; I find I have to use a sponge to wet an area and then use this cleaner to scrub the area, then use a sponge for most of the removal of the water and loose material.
