These don't need another positive review, but here it is:  They're great.  They seal against the counter and stove really well, and "disappear".  Now that it's been installed for a few days I don't even see it anymore.

I only needed one, so I'm attempting an off-label use for the second:  preventing water from dribbling out of the corner of the tub during showers.
