I purchased two of these rugs last year and I figured they wouldn’t hold up well, but it was a decent price for a “temporary” replacement.  My prior rug soaked up water and stained and I figured this one would do the same.   I’m happy to say that one year later that has not been the case and they will probably last a few more years at this rate!  We use our porch a lot in the summer and this rug has been walked on, wet with pool water, drinks spilled on it, soaked with rain blowing into the porch and COVERED in the Spring’s pollen…..and they both still look brand new.    They wash off well with a water hose and the water didn’t even soak through when washed - repelled right off and dried quickly in the sun.  No loose threading either.    Great purchase!! 
Downside: They are now out of stock - bummer.   I hope they come in soon as I need a bigger size.
