I use it because as a DJ I want to have all my gear plugged into a single source without a ground buzz. Also is tells me the amps and volts, so I know I wont trip a breaker.
I didnt buy it tho....it was a gift from another DJ I work with.
That monster surge protector is worth every penny. it is a real surge prtector, not just a multiport extension cord with a fuse. The 6125-joule rating makes it take one hell of a spike to damage anything plugged into it. If you have expensive gear it is worth it to protect it. If you have a $300 walmart tv and $100 stereo, then a $200 surge device is certainly not needed, but for a several thousand dollar tv and a home theater system upwards of 10 grand, that extra piece of mind is worth the $200.
IIRC Monster used to(maybe still do) offer up to $100,000 of protection for anything damaged while plugged into their product. They make even higher end units that are the size of components in your rack. Makes me miss my krell amp and martin logans. Damn apt. life.
