Product review (4 stars): As expected.
They appear to work as intended, blocking the gap between counter and stove so stuff doesn't fall into the void, never to be seen again.  They don't really "stick" to the stove or the counter, but the silicone gives it a little bit of grip so they don't slide everywhere all the time.  The clear is really a thick translucent, which may or may not be a look you want.  Not glass-clear.  I have butcher-block countertops and a white stove, so it seemed like the least offensive option.  I am pleased with this purchase and I understood what I was buying, this is not fancy or hi-tech.
