Purchased a copper chef induction cook top. Using the copper chef pan as provided, the temperature when set at sear mode only went to 141 degrees. The cook top is brand new. I found two phone numbers to contact the company neither of which would do anything but ring busy 4 times then cut off. Don't believe the hype you see on You Tube. There is no one to contact at customer service to obtain a Return Authorization. I have been taken! Don't let that happen to you.
