Query: No Good.

This seemed like the perfect solution for me. I have a receiver with two Optical inputs and 3 devices I need to plug in (Blue-Ray, PS2 and AppleTV).Unfortunately, it seems this device causes enough of a "signal" loss to make it useless. I can see some red light coming through, but apparently not enough for my receiver to pick up and use. A shame. I would return but was cheap enough to not bother...I'll save you the trouble!
