I've been using two old 2.4GHz devices for more than three years. The service is consistently good and met my expectations. I have a set in my garage that connects to a standard definition satellite receiver and a CRT TV. It works well at a transmission distance of about 40 feet and goes through two walls and the roof of a garage. The other feeds an HD satellite receiver through two interior walls to a small flat screen TV in my kitchen. The result isn't HD on a kitchen appliance, but is cleaner than a regular SD feed in my opinion. In neither case was it practical to lay cables, and in both cases the received signal was clear and visible. (And I'm a broadcast/video producer, so I don't see horrible signals.) It's important to carefully read and set up the instructions, and then experiment with antenna placement. If you have large metal objects (such as a large CRT TV) near the transmitter and place them between the transmitter and receiver, you will have trouble transmitting a signal through them. Put the transmitter in a place where it won't be blocked by a large electronic device and you'll get better reception. The X10 2.4GHz receiver is subject to interference from our high-powered kitchen microwave at a distance of about 10 feet, and there are occasional bursts of static electricity. This is a bandwidth artifact. So if you use a microwave all the time and want the X10 receiver to hear it, you should definitely get the latest model. You may also notice some interference when using a laptop that uses Wi-Fi very close to the receiver, but it's intermittent. Aside from those fairly predictable clutter points, our reception is clean and clear 98% of the time. Since I avoided the thousands of dollars in remodeling that would have been required to run the cables in the locations in question, I think this is an excellent compromise. These are inexpensive devices that offer great convenience and give you a nice clean signal with the occasional static issue that has more to do with the range they operate than the devices themselves. If you're on a 55-inch flat screen If you want to broadcast an HD signal throughout your home, this is NOT the way to go. But if you want to send a signal to a small TV in a place like a kitchen or study, they can do a very good job for you. I gave it four stars because it does exactly what it's designed to do and while it's not perfect, it gets the job done and saves you money and repairs.
