About Gooseneck Mobile Phone Holder Products: ▶The phone holder is 50 cm/19.7 inches long, which can keep the phone at a proper distance from the eyes to protect eyesight. ▶Easy to install, no need to drill. Just rotate the bracket to install. ▶Our mobile phone holder is made of aluminum-magnesium alloy solid wire, which has better bending performance and longer service life. ▶It can be rotated arbitrarily, supports any angle, and the soft silicon layer will not damage the phone at any angle in the fixture. ▶The 360°bendable clip phone mount allows you to bend your arms at any comfortable viewing angle and reduce neck strain. Use Suggestions: 1. It is recommended to bend the gooseneck arm into an "S" or "Z" shape to provide better stability. 2. It is recommended that you use both hands when adjusting the angle: hold the base with one hand and bend your arms with the other. 3. It is not recommended to use it to hold the phone for typing or reading, because it will shake a little. The flexible arm is mainly used for watching videos.
