Product review (4 stars): Heat and Stain resistant - Does the job well.
This is holding up well so far - I have had it for a couple of months.  It needs to be cleaned frequently as I use my stove a lot.  It is keeping all the splatters and gook out of the space between my counter and stove and works well even though my stove is close to 2 inches above my counters.  It is very heat proof and has not curled or changed color even when exposed to lots of prolonged heat.  I have spilled tomato, beets, wine and pomegranate on it without staining it, so it will probably work well for you.
