This base fits the umbrella perfectly. My only complaint is the spout is tiny! It’s just big enough for the hose, but we really wanted to fill ours with sand (so it’d be heavier) and there is no easy way to get sand in each piece. We settled for filling it with water and set some big flower pots on top to add ax little more weight (and to pretty up the patio). Overall, I would definitely buy it again, but won’t plan on using sand in the future.
