The other reviewers have left out one critical issue with this device. IT MAY INTERFERE WITH OTHER RF DEVICES AND REMOTES IN YOUR HOUSE. I KNOW FOR SURE IT INTERFERES WITH ZIGBEE.I have a house full of remotes based on zigbee protocol. I purchased this item to control one of my A/V receviers in a closet that is not on my zigbee system. I thought this would be easier than getting more custom programming for zigbee. Before installing this remote, my other system was ROCK SOLID. Every command went through every time. After plugging this receiver in, I immediately started having problems with missed commands on my other system. I was able to prove to myself that the Next Gen remote was the issue because when I unplugged it, all of my other problems went away.I really wanted the remote to work for me - it's a great concept. Just beware that if you have other RF sytems in your house, it may cause unforseen problems.
