I bought this one for my 6 quartz instant pot since the original set does not include the accesories.
And this is just what I need, perfect size and you can steam eggs, vegetable even make cheesecake with the spring form!
You do have to used partchment paper for layering the spring form so it easily to take out the cheesecake later, but it so easily to clean.
The price is not bad and good comparing to other seller.
