Product review (4 stars): It fills the gap but needed to be trimmed.
I built my own cabinets and purposely didn't leave much of a gap on either side of the stove because I never wanted to fish anything out that happened to fall down through that opening. It did stop all the hardware from slipping through but liquids still made it down there and the stove had to be pulled out to clean off the cabinet sides. This cover solved that problem but since my gap was about as wide as the piece that should fit into it I had a lot of the cover on my countertop and really didn't like the look of it so I trimmed it down and now it looks much better. Its not a thing of beauty and even though the description states it comes in three stylish colors but the choices were black, white and clear so I went with the black and it really stands out on a brown countertop but the stove has black trim so I guess it was the best choice. It is not easy to cut it lengthwise and have a straight cut so I clamped it down on a workbench with a metal straightedge on it to be able to get a nice clean cut with a utility knife with a new blade. I would not think using scissors would have given me such a clean cut but who knows. I would have preferred it went all the way to the backsplash but paying 5-bucks more to get four more inches in length just wasn't worth it. If the gap you're filling is small like mine then youll have about an inch of this on your countertops on both sides but for 10-bucks I cant complain.
