The cable itself is great. There are plenty of reviews here to back that up. The issue that I have been having is that sometimes the off setting works a little too well. In my personal experience, I haven't been plugging into a hot amp or sound system as much as I thought I would be (I still tend to plug in before the power is on, or to be sure the line is muted). More often what has happened is that during a hurried sound check the issue with sending out no signal was simply due to the cable's circuit breaker switch not being turned on. The same thing has happened when others have borrowed my cable and weren't even aware of the on/off function.
