Stand U is a device that can mount a smartphone or tablet. The body is made of aluminum and is designed to be strong, in the form of an iMac, so it feels as if you are seeing a small iMac. A powerful neodymium magnet allows smart devices to be mounted on a Stand U. Because magnets are powerful, small force can be rotated at 360 degrees while mounted on a Stand U, which facilitates horizontal or vertical rotation of smart devices. And it is designed to tilt with a little effort. The tilt is about 15 degrees. EVA foam is attached to the bottom so that it does not slip on the desk. The maximum size that can be mounted on a Stand U is either the iPad Pro or ASUS MB161B+ (15.6-inch portable monitor). Attach the product's steel plate to the center of the diagonal line on the back of the Smart Device that you want to use, and after approximately 30 minutes, it is fully bonded before use. When using the smartphone on the table, the height of the smartphone is close to the eye level to reduce neck strain.
