The product arrived quickly.  It is large enough for me to clean even very large silver pieces.  A pair of earrings that were badly tarnished, and unwearable - to my way of thinking, were sitting on my desk for the trial run and they are beautiful now - they look brand new.  Tarnish residue was left on my fingers - but that's part of the process, last I checked.
Unfortunately, it seems that some people received and instruction card with the cloth?  This was not the case with my order, therefore, I gave it only four stars.
