Although it was easy to assemble, the metal locks included do not fit in order to hold the four individual units together. I am not happy about this. We tried every position pushing continuously trying to get the metal parts to lock, with no success.
Perfect weighted stand. Keeps 360 degree tilt cantilever umbrella sturdy. Easy to install. Filled each section with water with nearby hose. I believe each section, when filled, weighs approximately 30lbs. each. Then simply paced each piece accordingly and attached the brackets.
Works great, looks nice and assembled nicely. The only issue was filling it with sand. I wanted to fill just once and choose to use sand over water but with the small hole it look forever.
