Demonstrate Extension and Retraction

What happens here

The reviewer demonstrates how the telescopic ladder operates. He unhooks a strap that secures the ladder in its compact form and then manually extends the rungs upwards, showing how each section locks into place with an audible click. He then quickly demonstrates retracting the ladder by pressing release buttons on the rungs, allowing it to collapse back down into a compact size.

Goal: Showcase the ladder's telescopic mechanism for easy deployment and storage.
