They are great, I have two children and we like to travel, but there is only so many times that you can hear "Child Songs" Vols. 1- 15 without actually pulling over and ripping your ears off, anyways they can jam to "Mary had a little lamb" like 50 times in a row and I still have my sanity, only if they worked up front so I could escape my wife.

Just curious, has anyone else been saved by these things?
