Product review (4 stars): Fills the Gap and Stays in Place
I am a self-proclaimed "Messy Marvin"; I just am.  Clumsy, clutzy, sloppy, messy... so many adjectives to describe the walking disaster area that I am.  However, I LOVE to create in the kitchen--cooking, baking, prepping; it's all fun to me. The trail that I leave behind me is not so much fun.  And, it seems that whenever I try to be most careful, THAT's when something explodes or oozes down the counter, or (inevitably) between the counter and the stove.  Therefore, I had been searching for a "gap-filler" for just this purpose.  I have looked at so many different ones, added them to my Amazon cart, then changed my mind for one reason or another.
When I stumbled across this set, I decided to take the plunge.  I was pleasantly surprised to discover how pliable they are--I kept thinking that there's no way any of these crack-covers will fit my uneven counter tops.  Low and behold, a little silicone is all it takes to save the day.  They set nicely in place and because of the tackiness of the silicone, stay in place.  This,  though, also attracts lots of dust and fuzz, too, so you'll need to be sure to wipe them frequently.  I find that my Norwex kitchen cloth removes the lint with ease.  Black seam protectors may not show the dirt as readily, though, as the white ones.
The set in the stock photo when I'd ordered them was black, so I had expected to receive them in black.  Mine arrived as White.  At first I was bothered by the discrepancy, since my stove-top is black and counters are dark.  The body of my stove is white, though, so it really is not too clashing.
Overall, my opinion of these is favorable and lines up with the company's statements:
