Product review (5 stars): Not a romantic item, but work great!
I wasn't even sure there would be something called a "stove gap seal" but I was happy to find these when I looked on Amazon.  The first one fit easily into the gap on one side of my stove.  The gap on the other side of my stove was uneven and basically closed as it moved towards the back of the stove, so I had to use some muscle to push the stove to make room for it and push it down.  I eventually got it in there.

The gap seals look very good and are the exact right length for my stove.  I have a new LG oven.  Highly recommend!
