Weber Rust-Resistant 22" Round Griddle Insert

Does anyone have this Weber griddle insert and using it?

The Weber website hasn't had it available for months, but it is available from several websites including HomeDepot, ACE etc.

Seems like a decent unit, but I don't see much discussion on it.

I am curious at how good the air-flow is?
I have a Manturion griddle and it gets plenty.

I never heard of a Manchurian Griddle, so of course I had to Google it.  I came across this earlier WKC forum post -

What a interesting accessory.  It seems like that would be a unicorn find.  I would love to have something like that.  So functional!
