Porcelain enamel cookware on glass cooktop?

I just purchased a set of Rachael Ray’s Porcelain Nonstick Cookware. The brochure inside says not recommended for glass/ceramic cooktops and Maytag says to follow cookware manufacturers recommendations but I’ve seen many reviews saying people don’t have problems as long as they don’t let the pans boil dry or use high heat for extended periods of time. Anyone out there who has used these pans on a glass cooktop? Results? Thanks!
