We have a huge problem with remotes in my household. We keep losing them, or maybe we are just too lazy to look around. In any case I have bought four of these. They work on everything I need. Panasonic tv, Cox cable box, and Sony tv in the bedroom.I now have two for the living room for when we lose the first one, one for the bedroom, and a spare in the garage I bought when I lost both the living room remotes. Easy to program and also has auto search for if you lose the codes. For less than $10 a pop these are easily worth the money and I'm not going to go so far as say disposable, but when I lose one its not the end of the world. All in all a good buy.
