The USM-2 consists of a plastic platform with a hole for the mobile camera.
Four metal holders can be adjusted in a cross shape to grip the mobile phone and fix it in the desired position, so that the camera is centered in the hole. Behind the hole is a smart three-armed "grabbing claw" with rubber-padded claws that eccentrically grips your eyepiece with the help of a set screw. There are memory markers on the front, so you can memorize which position you were on the phone last. Even mobile phones with the camera high up in one corner can be fixed, even if they stick out a little along one long side of the holder. It also comes with a couple of spacers in self-adhesive rubber, if you have a mobile camera that sticks out a bit from the mobile (for example, some Samsung models). This is to ensure that the mobile phone lies completely flat in the holder. You can choose to have the holder lying down for landscape mode, or standing up for portrait mode.
