Owned this mat for about 9 months now, holding up very very well so far.  Winters are pretty bad in Cleveland and even with all the snow and salt and spring time mud wiped on this mat it has held up nicely.  The same as pretty much any other mat it does show salt stains (especially on black) if it's not cleaned  2-3 times a month. Stays in place on tile with nothing extra to hold it down and sturdy/stiff enough to get shoes clean.
