When we got this we were still using our old cookware. We were suprised that its design allowed us to use it over our older 3 quart saucepan. This steamer works extremely well and very quickly. Its all a matter of getting everything to a similar size during food prep.
When we got our All-Clad pans, we discovered this steamer fits over both our 3 and 4 quart sauce pans. Using the 3 quart and less water to boil to get us the steam, the steamer works wonderfully. Due to our health problems, steaming our foods is something we now enjoy as part of our new diet. Clean up couldn't be easier, we pop it into the dishwasher and out it comes all shiney. We love this steamer. You can use it over almost any 3 or 4 quart saucepan.
