Arrived quickly and works as a keychain for my Samsung Plasma. I'm so glad I now have a NORMAL easy to use controller instead of the original stupid BN59-01134B. This thing literally ate batteries and was too difficult to use. Eventually it stopped working, thank goodness, and I found out that a replacement costs $60. Probably a nice gentleman left in his review the advice to choose AA59-00442A instead. I'm very grateful
