Before I even got to use the large 3 qt pot, it slipped from my hands and fell to the floor.  I couldn't believe it, but it ended up out-of-round, not dented, but flat in one spot.  The lid doesn't even fit.  I have dropped  4 different brands of pots at one time or another and none of the flattened.  I do have a call into Ninja.  Hopefully they have a repair area, it was my fault, but I never even got to use it.
