Its a smart base but over the last two days that I've had it, the parasol has fallen over twice. It's  not even been very windy. Disappointed its not heavy enough in a very light breeze. 

I saw from a different reviewer that this was a problem, but since there were a lack of complaints, I thoughr it was a one off. I am going to have to do what they ended up doing and either add bricks on top.
