Edit: Since early 2016, it is now possible to purchase multiple remotes and operate them in the same household without issue
Thanks for your interest in the remote. Unfortunately for you, the remote is usable at extreme distances, and works when I am in other rooms. I cannot truthfully recommend you purchase more than one, as you will probably experience some interference. What you could do is order one, go in to your other room and try and see if you can control your TV from there. If you’re not getting any interference, then you can order another remote from us (we’ll waive shipping for the second unit).
