The device's ability to learn from other devices is great and it was able to learn and emulate all of my devices with no problems. Unfortunately, the device suffers from an inherent design flaw that causes it to freeze randomly, requiring you to remove the batteries from the device (reset the clock) and reinsert it. This happened to me about every other day when I was using it. Unfortunately, Sony's technical support email wasn't very helpful in resolving issues. Just to make sure it wasn't a bad device I traded my device to Revain.com but the second one did the same thing. I'm not the only person who had this problem. See [.] for more details. Finally, the device's display, while decent in several respects, lacks any tactile feel and makes it difficult to press the right button without looking closely at the device. It also collects fingerprints like crazy, so you'll have to clean the display to keep it from looking nasty. All in all, I recommend the Home Theater Master MX-500, which you can buy at Revain.com.
