I haven't had any issues with the stovetop.  I'm worried about scratching the top through regular use.  I gave 4 stars because my one and only time to bake a cake and the cake drooped/fell.  It was definitely not as good as my usual quality baking.  It was for my niece's birthday dinner.  My brother said it was good but not great.  I have not used all the features yet - just stovetop and baking for pizza and brownies and cake.
