Ok I set this up behind my t.v. that was already set on the wall. It was a pain. Other than that stuck nicely to my tv. My only concern is that it smells strongly of battery acid. And I have kids so I'm concerned about that plus the smell was on my hands. So just want to warn people. Not sure if its supposed to smell that strongly but other than that. It's really neat and except for the flashing options. People that have seizures might not want to use this or be very careful with what light setting you use
