This was a replacement stand for the Kelton 10' umbrella I purchased (which is wonderful).  The original stand I bought for this particular umbrella (Annapolis) was not heavy enough to support, although it was pictured with this umbrella.  So I contacted customer service (who were very kind) and chose THIS stand because it was heavier.  I'm STILL having the same issues with this stand not being able to support the weight of the umbrella.  I'm writing all of this to say, if you plan on purchasing a 10' umbrella THESE stands are not heavy enough to support the umbrella.  If a lighter weight, smaller umbrella is being used with THIS base...then it would be perfect.
