Product review (5 stars): OMG what took me so long!
ok these are amazing, I had heard rumors of something like this, some strange contraption that blocked the space between the stove/oven and counters so no more crumbs/messes in that little space that seems impossible to avoid no matter how hard you try.  I would have never called it a stove-top extender or found it if it wasn't just dumb luck.  It IS an extender for the stove/oven and title is appropriate but WHO looks for that? WHO has ever heard of that?  Have I been hidden in a cave for a tremendous amount of years that this is the first time I've found this?
I love the magnetic edge so NO crumbs/spills/messes CAN fall over the edge of the stove top.  The very end of MY oven has a plastic type oven control knob holder so I had to trim it slightly shorter but that was simple and now fits perfect.  I will always have these and even want to check out familys' kitchens closer (not something you usually pay attention to, at least not me) to see if they can use them as part of Xmas presents!
