Amazing build quality and you won't find a $70 'slider'. I have a gimbal plate for my GoPro h9 and use my phone to control the controls. I also shoot in 4K on my phone with a tip from another reviewer! Use another phone or iPad to control it as if it were another camera mounted on a slider. People gave good reviews when sold for 300+ or whatever. So for $70 I can't complain that I spent more on a phone case.
