First off.. where else can you get a quality electric burner for only 9 bucks? This burner has exceeded my expectations to be honest. It works just as fast as a regular stove, and cools down at a reasonable time. When I first used it, there was a strong burning, ashy smell coming out of it so I thought it was going to explode or something, but it didn't. So don't be worried if you first smell that. After a few times of using it, the smell completely goes away after you turn it on. The rings also turn orange when it's in use, and it turns back to black after 30 seconds of turning it off. I'm super happy with this burner and the price!
