This has been in use on my deck for about 6 weeks now. There  was only a small umbrella that was not even open in the stand. I came out to find, what i can only imagine was a small wind, destroyed the base and it’s totally unusable now. There is cement powder all over (I cleaned it prio to the photo). My grandkids little yikes picnic table umbrella was undamaged as was my table umbrella. What a waste of money!
