I just picked up a Home Logic HL-UR400 which is the same unit described above. It was also missing the warranty card and batteries, but I got it from a store, so I don't expect any problems. I may have to take it back because it doesn't "beep," but I probably don't want it to beep. It works as described and the macro function works. It learned my entire system in about one hour, including learning how to use it and doing some things over several times because I couldn't quite figure out how to match the supplied icons with the OEM remote buttons. My JVC dolby digital receiver has separate on and off inputs from the remote, but I simply picked some other function key for off and let it learn the off the JVC remote. I'm happy with it. My wife even figured out how to turn the volume down after I programmed it--beats having her yell in my ear and hit me while I fumble in the dark for the right remote.
