The product does what's supposed to do, not all function buttons with me (Linux - Ubuntu 10.04). The remote control is ready for use immediately after stuck inside. If the preconfigured key assignments do not like that with the help of certain software can be customized. The only major drawback (for me personally) was that only the one supplied with the remote adapter works together. One has to say so only one choice ... The adapter also works with "Lirc".
Addendum: If you want to buy a universal IR USB adapter for any remotes, I would recommend this here "TechnoTrend USB Remote Receiver Kit". Works fine on Linux (Ubuntu 10.04) in conjunction with "Lirc".
