Bought this in the lime green, looks wonderful on our deck, lots of coverage and seems well made for the price.  We purchased 4 square paving stones (to weight the base) at our local patio supply store for a very reasonable cost, their total weight is 180 pounds which should be enough for a bit of wind (which we get in our area).  It covers a seating area on our deck adjacent to the dining table which has another umbrella....can hardly wait for warm weather so we can truly test it out!!!
