We are very happy with our purchase. Before buying this Umbrella stand we had made our own with a large wood flower pot filled with stones. It would blow over in a gust of wind- spewing stones everywhere. 
The BCP Fillable Mobile Umbrella Stand with wheels is exceptionally sturdy. We finally feel confident enough to keep our umbrella up and walk away. We’ve had it for about 3 weeks and have been able to have our umbrella open, even on breezy days. We filled ours with water and it is very sturdy, easy to move around too. 
So glad we made this purchase, well worth it. It arrived when expected and packaged well.
