Wow!  Super heavy. Perfect to hold our patio umbrellas from toppling over in heavy winds. I ordered two and the first one I unwrapped was slightly damaged, the corner was chipped, but with a little brown paint to cover the solid concrete chip it will be fine for what I need it for. The chip will be hidden. That is why I gave 4 stars, maybe the packaging should be doubled at the four corners to prevent it from happening
