I have microfiber cleaning cloths in the past so I am familiar with them.  What I enjoyed with the Frigidaire brand was the size most of all and the reuse capabilities. The cloths are a good size and can be used with a cleaning product or with water.   They have just enough "scrubbers" to them that one doesn't have to rub the surface being cleaned too much.  I bought additional cloths after trying them out (when I find a product I like I usually purchase additional after testing).
