So I’m giving 3 stars because it does work in keeping my outdoor wooden table dry and is true to size.  The price was probably too low but I thought I’d try it anyway.
I don’t anticipate it will last long though as the material is so thin and feels like it’d snag on just about anything.  It’s so thin I truly didn’t think it would be water resistant but so far so good.
I doubt it will stand up to winter weather.
