This device satisfied my needs and is ruggedly constructed; it's simple and therefore it worked as expected. However, there is one issue, and that's why I've given it four stars instead of five..
I use this as an interface to connect my computer speakers to my small Behringer mixer. A few days ago I realised that the left and right channels were coming out of the wrong side. After going through all my software settings, I eventually tracked the cause down to the fact that this adapter is incorrectly colour coded, so instead of the right channel being red, and left channel white, it's the other way around. This is easily remedied, of course, by just switching the plugs around, but the fact is that this should not be necessary. It being so inexpensive too sways me in favour of four stars instead of five, because it makes it good value despite the one fault.
