Review on Duxtop LCD Portable Double Induction Cooktop 1800W: A High-Performance Electric Countertop Burner with Sensor Touch Stove - 9620LS/BT-350DZ by Jonathan Davenport

I have two old Duxtop burners one of which broke down after many uses and they worked so well I decided to buy this new two burner model but it doesn't heat up as quickly like mine old single burner. Not sure if it's on purpose, but I've found that it doesn't boil water as quickly and pans don't heat up as quickly. One example I noticed is when I tried to pop popcorn in a pan and it didn't even pop on the highest setting. I pulled out one of my old working Duxtop singles and it started popping very quickly at a much lower temp. I will contact Duxtop regarding this and hope it is just a defective unit.
