Bill, Matthew, Liza: thank you! After hearing your reviews, now I’m completely sold on it…and won’t feel like I am just buying a frivolous gadget. Funny thing is, I saw this pop up when I did my Amazon search, but had no idea it was expandable and didn’t read down to see the description. It’s pretty reasonable, too! Okay, I admit my quiche crusts (leek, goat cheese, & bacon; and spinach/mushroom) came out just fine tonight even though I was lacking this ring, but it just seems like a fun thing to have, and useful too! Thanks again for the info!
