Should I Buy Calphalon Cookware As A Gift?

Simply Calphalon is having a 20% off sale and I was thinking of buying online. This is for a wedding gift. Also what would you buy from the catalog. I'm leaning towards buying Calphalon Unison Nonstick 1-qt. Sauce with Cover.

How good is the nonstick surface and for how long does it stay nonstick.

Have you tried it and if so would you recommend it.
