Brass Shank 400A

I know I've asked this before but I'll try again.

Anyone seen / Used the new Fluidmaster 400A W/ BRASS SHANK ??

Saw it in a trade magazine and have asked around at my supply house. Can't seem to get a grasp on them yet.

Anybody like or dislike ?? Seems like a great idea.

I'll take a case if I can get them for $4.62 a piece.

The are Fluidmaster's new "professional line", (about a dollar more than the all plastic Pro 400A which is the one with the red cap), and they advertise, "Plumbers will find them innovative. Amateurs won't find them at all."
