I'm selling this because I haven't used it much. I was using it for a 15.6-inch mobile monitor. ● Product Details [Applicable to 12.9-inch tablets] Compatible with iPad Pro 12.9 inch, iPad Pro 10.5 inch, iPad Pro 9.7 inch, Switch, iPad Air, iPad Air Mini, iPad Air 2, iPad Mini 2, iPad Mini 3, iPad Mini 4, iPhone X, iPhone XS, iPhone XS Max, iPhone XR, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, Kindle Fire HD, Android Nexus 7, REGZA Xperia Galaxy ARROWS tab, and SONY models!

Includes three types of brackets for tablets, smartphones, and Switch] In addition to tablets and smartphones, it comes with a bracket for Switch, allowing you to comfortably watch videos or play games while lying in bed or on the sofa, making your hands more relaxed. [World's first four-joint arm, two ball joints] This product was developed by our Unique Spirit store with a focus on functionality. As the world's first arm to adopt four joints, you can adjust the angle and direction more freely. By adopting two ball joints, it has a higher degree of freedom than general arms, making it much easier to use, and you can comfortably use your device whether it's horizontal or vertical. It can be folded when not in use, saving space. [Newly developed special clamp] The clamp has six insertion holes for the arm, and is structured so that it can be installed in various directions in various places, such as tables, pillars, and bed headboards, expanding the options for installation locations. You can attach it not only to the side of the bed, but also vertically to the headboard. The clamp has a wide clamping thickness range (up to 52mm), making it possible to attach it to various places, which is very convenient.
