Product review (5 stars): Perfect!!
I really wish I could remodel my kitchen and put in a built in range but until then, these are the next best thing. It's an "L" shaped cover that magnetizes to your range and covers that gap between your range and the counter top.  It's very low profile so I don't even notice it at all anymore. It definitely keeps grease splatters and crumbs from falling down into the dark abyss between the stove and counter, but I don't think this will keep big spills from dripping down into it.

I loved mine so much I bought a set for my husband's best friend, who up until then, was using electrical tape to cover that gap and he loves them too!
