We have owned this oven for 10 months and absolutely love it. I even started a new hobby of baking bread! Last week I was boiling water in a small sauce pan on the large burner and heard a loud pop. sounded like water may have splashed on the oven top and made it crackle. When I took the pan off the top I noticed a small piece of glass missing and several fine cracks around it. The manufactures warranty he is going to replace the glass top but now I am concerned that this is going to be a regular thing.
