purchased three of these (discontinued by manf.) for all big screen tvs; Still bear of a job to clean, esp., the 55 jnch plasma but they have been a help. Had to use extra cleaning pads and had to redue three times but still was great help. Closeout price was only $1.99 each so i really could not go wrong.Nice!Seems to work pretty well. Just used it on my 52" Sony two days ago and it really cleaned it up.
