Query: Very Convienient!

This is quite an amazing product. If you have more than one device to plug into the TV, plug them all into this. Then, once you turn one of them on, this will automatically change the input to what was turned on. So there is really no work whatsoever when switching between inputs. The only annoying thing is that unless it's on the floor, it tips over backwards really easily from the weight of the cables.
