That would be to shoot handheld video or to shoot motorized pans/sweeps (you can set up motion points with the phone app and have it move between at a programmed speeds). This lets you do motion timelapses. Contrary to what you said the Crane M2 is one of the smallest and lightest gimbals for the purposes I want.The price is about right. There are a lot of compromises with the size. What exactly are you doing with it and the Chinese stabilizer device? It seems that defeats part of the portability.
