Great product - easy to assemble. I used sand only and 45 mph winds will not move the umbrellas with the wheels locked.
We love this rolling base because it is NOT heavy, it is attractive, and it works.
Friends of ours have lovely umbrellas that tilt but all of the bases weigh a ton, and they cannot move the bases around the pool deck or backyard area.
We do like the base, but are going to take a few bricks out so it is easier for us to move. It sure is heavy for us old folks.
Other than that we are happy with our purchase.
