Who, like me, also uses his PS3 to play Blu-Rays and a Logitech Harmony calls his own, which I can only recommend this adapter. Because so you can banish the PS3 controller, or the PS3 remote control in the drawer. The adapter comes with a power supply and a sufficiently long power cable, and a Quick Start Guide, which is but perfectly adequate. The connection to the PS3 works without problems. Yet set up the Harmony remote for the PS3 and now you can use all functions and remote controller features.
The price may not be a bargain level, but you get used to good Logitech quality with flawless compatibility.
