Product review (4 stars): I've found two uses for these
The gap between my range and the kitchen counter is a catch-all.  The gap is small -- just an inch or so -- and it's amazing, the stuff that finds its way into the gap, and down the side of the range.  I'm lucky in that the range is at the end of the counter, so it's fairly easy to slide the range out for cleaning.  But with these guards, I won't have to do that anymore!

These guards are magnetized so they stay in place.  They fit neatly.  That's all I need.

I only needed one of the guards and didn't know where to store the second one so I'd be able to find it if I needed it later.  Since it's magnetized, I stuck it on the side of the fridge. Then it hit me -- magnet -- fridge -- it will hold photos! It could almost have been made for that.
