Summary: You are paying under $10 a unit, so do not expect much, but they do what they are meant to do. Plus - Nice list included in the instructions with hundreds of codes makes this easy to setup. Minus - It feels like cheap, light, may-fall-apart plastic but I have only had them for 1 week so I cannot comment on durability, just on feel.
Summary: most complicated remote I ever seen . I still don't know if it functioned correctly or not. It did some things and not others. compared to the one I got to replace this one, a most difficult device.
Summary: I purchased this because the remote on my old Toshiba died. If you have never programmed a remote, as I had never done, just be prepared to be patient with yourself and this remote, and set aside some time. But the makers tried to be as helpful as possible. They give you 3 different ways to program. If I did it, anyone can! I've had a stroke so my fingers aren't nimble, nor my eyesight so great.
Summary: The remote works as advertised. The only minor issue I have is that the middle buttons between volume & channel sometimes get hit when I'm channel-surfing. If there was just a little more distance between the middle & edge buttons I wouldn't have that problem.
