ya, my little princess has kick the player once, i have told her to be careful or they wouldn't have movie to watch, sometime need to train the little person to take some "responsibility". Anyway this is just a cheap player that i can change it easily if broken, but at least should last for a year or two i think :D !
there is one place that inside the passenger glove box where BMW install DVD changes, i have took out the cover plate and found it is perfect to install the player. But i thought that it will be good to let the little girls to manage the movies and operate the player themselves .
This cheap player come with SD card reader, my little princess copy the movies they want to watch to the SD card everytime before the jurney. once again, i let her to manage herself too !

looks great, The one suggestion i'd make is to route the wires behind the seat back.. i think they come off pretty easily..
