Review on 📷 GVM Motorized Camera Slider: 31" Carbon Fiber Dolly Rail with APP Control, Time Lapse & Video Shot Features, Follow Focus, and Panoramic Shooting by Sheila Harp

I have two more sliders and this is my main slider. The ability to use a phone app for control relieves the amount of hardware that needs to be carried around. The motors are powerful enough to carry a 2.2-pound camera vertically. It's quiet, smooth and very easy to use. Setup took 4 minutes. Costs money.
