Shuttlecock durability spray????

Has anyone tried any of these products?

Am wondering if these are the equivalent of  snake oil  for the badminton world?

Found the following examples on the net.

Example-1

Example-2

Li-Ning shuttlecock with replaceable feathers

Found the following sample in one of the halls I frequent.

Here are close-up(s) of the shuttle.

Li-Ning shuttle with replacable feather rib-cage

2 replacable feathers removed from the shuttle

The tip of each of the feathers has been made into a uniform "shape" eg alike a chisel.

I called the local Li-Ning agent to enquire of the cost for replacement feathers.

Surprise surprise ...

Replacement feathers are not available separately. Only a few replacement feathers will be provided in every tube sold.

This is like discovering the wheel but then deciding to lock it away!!!

Guess the only thing which matters nowadays is the bottom line ...
