Title: Do you really need this?
Review: I did not notice any difference on my 52" LCD from 6' away. It sucked the life out of my batteries, twice. I must have left it on? The warning sound goes off after one or two hours but when you get playing you forget all about it. The blue LED light on the front is SO bright I had to cover part of it up with electrical tape.
