This worked beautifully for us. We have a patio with curved walls and a paver base. My only concern was if this was a trip hazard. Considering that we used it to keep a large umbrella in place to shade our seating area, this base was out of the way and not a concern. I live in the northeast and was worried about high winds knocking it over. It hasn't happened. It is kept closed unless we're going to use it and two different ties we had heavy rain and winds. It stayed in place perfectly. The handles make it easy to move and place it exactly where you want it. I am in my 60's and have arthritis in my hands and it was no problem for me to grab by the handles and move one at a time to place it where I wanted it. I would highly recommend this.
