I bought the nano bond after researching the company and taking the test. Hands down this has been the best set I have ever owned. I got tired of poor quality cooking sets and wanted to invest in something which would last for years plus cooks well. The pans are well balanced and clean up is a breeze. I love they could go into the dishwasher, which makes things easier. I cook on electric, I’m amazed how well the heat is dispersed evenly. I have coil now but will be going to induction eventually- i did use an induction cooktop burner during our kitchen remodel and the pans worked beautifully. 
Best investment I made. So happy I chose Hestan and nano bond.
