Great set all around. I used it with an optimus nova, coleman 2 burner propane, and right on the fire. You can also nest the msr stainless plates in this set as well as the alpine frypan but with 4 plates and frypan the last lid is slightly ajar. The 3liter pan is awesome to have for heating large amounts of water, soup, scrambling 2 1/2 dz eggs, etc.
So why 4 stars? Daddy needs a LARGE MSR alpine frypan.
