In my experience, dollies like that only work well when the ground is completely flat, level, and dry.
I have a park it 360 and an out of flat, level driveway and frankly the thing is a nightmare to use. Or when the ground is wet.
The one in the video seems to have a similar attachment method to the PI360, which is awful as well.
