I wanted a backup to my Samsung factory Remote control which came with the television. So as soon as this one arrived, I popped in a couple batteries in this previously owned control, and ran through all the buttons without any operational problems of any kind. After a thorough Inspected I can add that it only has a few ""very slight abrasions"" which don't affect the operation of the unit. Fast shipping, low cost, works like the original gets 5 Stars from me.
