I bought this today to strain my homemade yogurt. While it holds about 4 cups ultimately (waited a bit for some of the whey to drain, then added more), it allowed more "white" to wash into the "clear yellow" whey than I would have preferred...I think.  I'm planning to start making ricotta cheese from the leftover whey and I suppose that would capture the white milky yogurt that washed thru and convert it to ricotta.  My yogurt usually isn't really runny before straining, either.  However, after I strained the yogurt to the desired consistency, I took the remaining whey and sent it thru the gold mesh coffee filter and that captured most of what had escaped this OXO strainer.  It IS a good quality.  It IS large...so large in fact, I'm not sure how I'd put it in the fridge overnight to make yogurt cheese.  It would be helpful in the kitchen in other ways but where do I keep it in my very small kitchen?  It's probably going back for a more compact model of yogurt strainer that'll fit in the fridge.
