This cooktop works well. I like having five eyes instead of four. The reason for the three stars and is that the knobs are kind of in the way. They're at the front, and so I can't just slide something off of it. Also, the large eyes are on the back. That's what I usually need when I'm cooking, so it would have been more convenient for them to be on the front. However, I saw all of that when I bought it, so it's really my fault. It does, however, work perfectly.
