I bought this product to use backwards like many other reviews have said. Well it doesn't work so well. First thing if you are going to us it backwards make sure you can turn off one of your optical devices because it will not work if both devices are on and connected to this. Second I switch out optical plugs on it pretty often and now after about a year sound will drop out intermittently until I move the wires connected to it, then the sound will come back. I am assuming the ports are getting lose over time because its plastic. I wouldn't recommend this product at all. I am going to buy a switch with an actual switch button on it. Overall, yes this is a pretty cheap product but not worth the headache. You pay for what you get.
