I read when making a Mini 4 Pro a C1 low noise propellers are required. How do they effect power & battery life?
And what is this thing. I see it in kit bundles but no descriptions.

Your mystery object has nothing to do with drones, so I'm not sure where you're seeing it.
It's a collapsible stool.

It could be the top secret elevated Neo landing platform.   

Mini 4 Pro comes with the correct props for C1 or C0 operation.

Hi there,
thank you for reaching out.

Propellers specially made for DJI Mini 4 Pro produce less noise and have undergone precise dynamic balancing tests to provide higher aerodynamic efficiency and powerful thrust to the aircraft. May we please confirm which website you saw the bundled item on?

Should you have any other questions, kindly message us here for assistance. Thank you.

Thanks All, I understand on the propellers now.

As for the stool, I have been seeing the thing on several DJI seller combo adds where they offer a collection of bobbles and trinkets but did not suspect it was not a DJI item, now corrected I thank you. Many of the adds I seen did not mention it or a stool or seat. Its why I asked here.  Thank You. No way I'm going to sit on that thing.
