Used it 3 times ,so let start with 1st 2 timesSteak - medium heat ,medium size burner - good result3rd time - Pasta with clamsSame burner - same medium heatAdded some olive oil and .all oil after few minutes when pan got hot traveled to the rim creating nice big circle.Lifted , moved oil around-thought its going to stay at least a bit in the center - nopeBrrr -what's going on - I didn't purchase Koren barbecue grillCooled down ,wiped all oil and let's go to my garage - grabbed small level and mystery solvedInstead of flat pan I HAVE A PAN WITH DOME IN THE CENTER !$130.00 for pan which "bowed" after 2 cooking sessions ?Totally unacceptable!Money not well spent - I am not going to write which pans and which brand I've used before-long list but I thinkNinja should stick to blenders not cookwareReally Really BIG DISAPPOINTMENT-NOT A GOOD PRODUCT -POOR QUALITY FOR WHAT NINJA CLAIMSNOT 5 STARS FOR SURE
