This umbrella base will last forever.  We have had this base in a windy desert climate, hot southwestern exposure, and it has not aged at all.  This base is now 1.5 years old.  The umbrellas still hold firm in the stand, the tightening screw works perfectly.  This cement filled base will hold an umbrella sturdy in the windiest of weather conditions.  It rolls along the patio smoothly, as it did when new.  The finish has not chipped, and has not faded.  Great purchase.

Pros: Durable product, looks like new, yet 1.5 years old.  Keeps umbrella sturdy even in strong winds.
Cons: none
