The Number one feature of smooth cook tops is just that.... they are smooth and sleek giving your kitchen a more modern look. Also you can still use the counter top space when the burners are not engaged. Last the ease of clean up, spills can be wiped away. Little drips of sauces and crumbs can't fall down under the burner unit.
But there are cons to the smooth cook tops. They require special cleaning products. Some spills if baked on may not come off. And if abused the glass could scratch or break costing several hundred dollars to replace.
If you are considering purchasing new appliances try "going live". There are several live showrooms where you can actually cook on the products. Boil water , bake a sheet of cookies, or run dishes thru the dishwasher. While the current showrooms feature higher end products they are beneficial for any one who wants to test drive appliance's to help them narrow their selections. As always we are here to guide you when you need help with your Kitchen project.
