The pot is real. The ad isn't.

cook on a glass top radiant stove with Pyrex cookware

Mose use & care manuals for most of the brands with flat surface cooktops say glass isn't a very good conductor.  I think Glenn has used some a Visions pot or two on his GE.

Pyrex: use the wire spacer, just to be on the safe side.

Flat-bottomed CorningWare Pyroceram and VISIONS: not needed, though some cooks use "heat tamer" disks on electric coil burners.

Yes, both of us had the teflon coated-ones.  The teflon eventually wore off, but the pots & pans still are great with a spritz of Pam.
