I purchased this for my deck..  I used the bags provided, fills to roughly 200lbs of sand.  We have had numerous wind storms in last month, never moved (note that it was closed)  
When open, does not tip over.  
5++ eaze of installation. I'd say 10 mins it was done. Only 3 steps or so.   I love that it comes with a cover.  Helps minimize fading.  Only time will tell if it's truly a 5 star. Right now, very happy with it.
