Just about the ONLY umbrella base meeting the recommended weight for many outdoor umbrellas.

Can be loaded up to 80 pounds of sand and water, which is important when so many umbrella bases only weigh around 35 prounds.  Further, rather than a small hole for putting in water, sand or gravel, the whole top comes off -- making is easy to load and unload the weight.  Easy to move with wheels and a grab handle.

The base holds a 1.5 inch diameter pole, with grippers and an insert to make sure the base holds the pole security.  Great design!
