I have used this a few times now and I like it a lot, it's pretty nice. I love that it's a bit more lightweight than comparable traditional glass baking dishes. The dimensions aren't quite the same as other 9 x 13 baking dishes that I own - it's a bit more shallow and round than the rectangular dishes I own. It looks great, modern and eye-catching. I have used it in the oven with terrific results. I have used it to make tomato sauce pasta dishes and it hasn't stained or discolored at all. It's easy to clean and dishwasher safe.  My only dislike is that the lid is not even a little bit air tight, it just kind of clips on loosely, so I wouldn't use it to store leftovers or for travelling to a cookout or other gathering where I'd bring a food dish. Other than that, I like it!
