We bought the unit on 12/30/19 but finally got it installed by Best Buy this past Saturday on 1/18/20. We had an electrician install new 6/3 gauge wire and 50 amp breaker per installation guide to make sure there was no issues. Now after just a few days we could not turn off the unit. It became unresponsive while it was still on!!! I had to reset the unit by flipping the breaker off/on. The user guide has no troubleshooting for if the unit touch screen buttons do not respond. This is super disappointing after spending $2000 for the cooktop and electrician!! And off course now that it is installed it is showing in our BestBuy account that it is none returnable! Buyer beware! DO NOT BUY THIS PIECE OF JUNK!!!
