It installs quickly and easily. Menus very clear. In 10 minutes all motion. By cons, no ON / OFF button (besides no buttons, not even string changes) on the device. If your remote control fart ... bye bye demo (except remote redemption) so be careful. Otherwise NICKEL picture, I connected a USB HDD 750GB above all recognized formatted etc ... except not perfect-button. (I do not like being dependent on the remote)
