The Elgato Green Screen is the only one of its kind in terms of the overall package. You don't need nails to hang it up, you don't have to set up tripods that you have to break down every time, it takes up very little space, and so on. You can rotate the 2 feet of the Elgato Green Screen 360 degrees and position it however you want. In terms of purchase, it is more expensive than, for example, an average Green Screen set of, for example, 50-80 € which has a tripod that will fall over if anything hits it. But, all in all it is well worth it! I've had many green screens, but this is really a solution I can say.
I have never had such an easy-to-use green screen, and of course never so quickly stored a green screen in a very small space.
