Four remote controls were clearly three too many. But buy some universal remote control? Does it really with all devices? Especially when older are? Although one of my CD player CD 614 / 00B Philips is good example but has been at least a good 15 years on the hump! And all functions are really recognized and accepted? Because of such questions I have previously purchased any universal remote, so far! Eventually a colleague of mine has bought a Logitech Harmony 300 and the right raved about. He said that really recognizes all devices and can show the remote control buttons manually ultimately, if you still have the old original remotes. In the event that the database of Logitech is not complete. Ok, they have ordered me here then. Conclusion, my Kollge has spoken the truth! :) Even my old CD player has been recognized, however, had to learn manually the individual functions of Harmony. But worked great! It takes some time, however, and a computer. Does not matter, made me even this much fun. Is very good, that you really can occupy any button on the Harmony 300i with any command of the old original remote control. Big plus here, other than as described in the online documentation, must not take over the command of the old original remote control you. So, if standing on the old remote control "Track", you can call this on the Harmony just "title". Quite handy for some things! Conclusion: Now I've held four remote A only one that looks incidentally still looking great! A star I subtracted because a detail is solved very impractical. Is once a button on the Harmony occupied and you want to delete this one command, all key commands have to be deleted. After that, then everything will be reassigned. Is it very awkward. Nevertheless, I'm really excited about this universal remote control, especially for the price! A little tip at the end if you manually populated with the remote control commands, one should press the corresponding key 1 to 2 seconds. So loud Online. That's way too long, since there was only an error message. Very quick tap is enough because entirely.
