Logitech sells several models above the 550. Honestly, I cannot imagine what else you could possibly be missing from purchasing this remote. It is INCREDIBLE. The setup is easy and thorough. You can customize it beyond what you would imagine. Want your A/V receiver to be turned on after your DVD player? You got it! Want to have the remote say "Annoy Wife" when you want to play your Xbox? No problem! Was your DVR infrared receiver blocked by the stack of magazines on the coffee table? It can handle that. You just ask for help and it walks you through a few yes/no questions and BINGO the planets are back in alignment.GET THIS REMOTE! Heck, they even included a new set of batteries to replace the Duracells that it had in it when it shiped. Genius!
