This device allows you to set a control monitor on a remote control. Your screen will not be equipped with a security screw is made of carbon, so lightweight. I removed two stars for 2 reasons: - There is no manual, and installation is not so intuitive it looks, you will receive a padded envelope with items in a plastic bag and a bag of screws. So, just get on to understand assembly. - A single clamping point for the screen, it's a little bit to be very stable, so be careful to find the right dosage for it to be tight enough so that the screen does not rotate on the attachment point, but not too much as to smash the monitor frame. Apart from that, this device served its purpose.
