Product review (1 stars): Don't fit, and show every fingerprint
Deep enough but the squares are a bit too small to fit my burners (perhaps covers that fit over two burners vertically like the ones for electric stovetops would work better). Also all four arrived dented and/or scratched. Pretty disappointing but not worth the hassle of returning.
Update: I was able to use a pair of tin snips and alter these so they will fit now. I  don't recommend it though because the edges where I cut them are extremely sharp. It doesn't look very good either. I really think one long rectangular cover that would go over two burners at once would be much better. The real kicker though is that even if these covers fit better they would still not be a good buy to me...... they show every fingerprint, every speck of dust or crumb....... Easy to clean but you have to hold them somehow while you are cleaning them.
