This unique stand includes two universal holders: one for your pico projector and the other for your phone. Alternatively, it may also be used with two phones for videos, tutorials, or live stream video. PRIMARY USE: Pico Projectors (sold separately by third-party sellers on Amazon.com) are commonly used in the cookie decorating community. Unfortunately, the stands that come with them are usually too short, and are very flimsy. Arkon's Cookie Decorators Mount is different. It's a stand that is height-adjustable up to 43" tall, allowing you to position your projector at the perfect height every time you use it. Many cookie decorators want to use a pico projector and also be able to use their mobile phone to record cookie decorating videos. This functionality is easy with the Cookie Decorators Mount. Insert your phone into the holder clamped onto the pole/post of the stand and tilt it downward to capture the action. For most pico projectors, the phone holder on the top arm assembly is the best way to grip your projector (those less than 3.9" wide). However, the Cookie Decorators Mount also includes a camera adapter with standard 1/4"-20 threaded pattern, which is found on all pico projectors, digital video recorders, and cameras. SECONDARY USE: If you own two phones, you can be filming front-facing or overhead view videos with the phone holder on the top arm assembly. If in the overhead view position, you'll be able to use your phone mounted to the pole/shaft position to view the comments or your hand movements in a Facebook or Instagram live. Using two phones is also a great way to capture more than one camera angle for your videos. Both phone holders securely fit phones up to 3.9? wide, including Apple iPhone 11 Pro Max, iPhone 11 Pro, iPhone 11, iPhone XS Max, iPhone XS, iPhone XR, iPhone X, Samsung Galaxy Note 20 and Note 10, Galaxy S20, S10, and S9, and LG G6, G5, and G4.
