I was looking for a teleprompter that could be mounted on the top/screen of my MacBook Pro and let me talk to the built in camera. Using it with my mirrorless camera would be a bonus. On a MacBook, the edge mount is secure and adjustable enough to work well as a prompter, but on my MacBook, the top corners of the teleprompter ended up in the top corners of the video image, giving the obvious appearance of a prompter. If I adjusted the fasteners to sit higher, the phone (and text) would appear in the image. It's no good if I want to create the illusion of spontaneous verbal brilliance. It attaches well to my mirrorless camera and tripod. The hood protects against light. It is reliable and functional equipment. I don't know if other laptops have a longer focal length camera that might clip the teleprompter. In that case, it might work better for someone else. It works great just plugging into the camera and for that reason alone it's a great price for a teleprompter. If you have a laptop and no camera and are willing to put up with a bit of visual clutter, this is a solid choice.
