After moving to a home that has a new glass electric cooktop, I needed to replace the old mix and match pots and pans that date to our early days of marriage.  They were not recommended for this new cooktop, plus it was time for an update.  Once I grew accustomed to the concept of new cookware that was pretty, I could seethe functional advantages.  One piece of information I did not know was that non-stick cookware should not be used with oils or butter as the non-stick surface might be compromised Boo-hoo.  But, the variety of sizes in this set is perfect for almost all cooking needs. Clean up couldn't be easier, although glass lids are a challenge when greasy.  Very pleased with the product, the price and the rebate offered by the company!
