No option for zero stars so it gets an undeserved single star. Avoid this umbrella. Four base containers filled with water are not nearly enough weight to prevent it from sliding across the deck even in the slightest breeze had to add patio slabs, which look awful. Hardware (bolts and screws) already rusting after one month. Plastic sleeve on cantilever arm starting to fail. Lights stopped working after two weeks. But the worst problem is that it swings around a lot in light breezes and seems like it will flip over at any time, so I added a bungee cord to connect an umbrella rib to the main pole. This helps a little but it shouldn’t be necessary. Overall a poorly executed design. Would not buy it again.
