I love this stand and love that it has wheels. The seems leak water though on one side. You can put sand in it but for me I prefer water as the sand is alot heavier and would be harder to move around. I have contacted wayfair to see if there is something I can do about  the leaky seems. You could just keep filling it up every day but my main issue with the seem leak is that it makes my travertine slippery. Great looking stand though if you want to fill it with sand I would say go for it! 4 stars becuase it leaks when filled with water. I posted a pic with a 12  ft rectangle umbrella. With water it holds this huge umbrella steady
