My husband loaded all this stuff up to take to Goodwill.  It is so heavy it takes me two hands to lift it.  Nothing is heat proof, including the handles.  I've burned myself every time I've used these.  Put a potholder on the handle now, but it falls off half the time.
They also cannot go in the dishwasher.  A lid was accidental run thru the DW and came out gray and mottled.  It has to be reglazed, if that's even possible for a small amount of money.
I bought these because they were pretty and the cobalt blue matched my kitchen decor.  Stupid reason, I know, but pot is legal here in Colorado.  I had no idea I would have to develop muscles to use them.
The actual cooking function was fine, but they are not really non stick IMO.
