We bought this a few months ago with the motor accessory. I just really started using it and just love it!
It has to be the smoothest slider I’ve used and I have used a few.
With the motor in loop mode it gets to the end of the travel and starts back automatically. Great for an unattended camera for interview or a second camera.

We recently used it for our vintage scientist series.
