Excellent quality, strong and resistant material, I love that it has a triple layer of non-stick which is great and gives me confidence that my food will not burn.  The grips on each pan and pot are very well riveted and the grip is very secure.  The pans have a rubber-like material on the handle so that it does not slip while you hold it.  The lids are made of thick glass and rubberized on the edge for an emetic closure and thus avoid unwanted accidents, they also adapt to all pans and pots.  The tray is very practical and of comfortable size.  The spatulas are very nice and feel strong and sturdy.  The overall design is very elegant and I love it.  Easy to wash and fits very well in the dishwasher.  I am very happy it is the best set of pans I have ever had.  It is a very versatile pot and pan set and I highly recommend it.
