Works on my TV so much except that I can not find all necessary keys. It lacks the OK button to select something (I tried all were reached, just in case). So I can not pass the string to the HDM2 HDM3 eg (I can not switch the display of the box, on the screen of my computer or the screen of the Wii), which of mempêche really to use this product (a hand to switch off and on, I can do nothing.). Similarly, not possible to adjust the box above what would have been handy.
