I didn't care what color I got as long as my umbrellas did not flip over.  I have a windy backyard, especially around 1pm to 4pm.  My old umbrella base was totally useless. I had to pile 10 bricks on the base just to keep it from tipping over, not very attractive.  These bases are study and heavy, no wind will ever tip these over. 

Pros: Heavy, umbrellas fit nicely and don't rotate around.
Cons: Heavy, they weigh a lot. Don't drop one on your toe.
