I bought this rug as a buffer between my back porch & the rest of the house to cover a floor that gets slippery when it's wet.  So far its been very effective & since it's synthetic it should last many years.  The only issue I had right after unpacking was that it was curled so tightly I had to fold it over under itself & walk on it that way awhile to flatten it out or I would have tripped over any exposed edge.  Now that the curl is out it lays flat & works well.
