I got some really excellent range with it.. but for it to work all the time the limits would be around 20-25 feet as you mentioned.. the only issue I have is that you can't control the MENU button on the iPod with the remote.. I like to have it sitting on my desk a few feet away... connected to my Logitech speakers of my new Sony headphones.. I don't have to fiddle with the iPod.. I just hit the remote and it moves to the next song and what not.. Excellent device..
