This item may work well attached to a fixed location, but attaching it to a push golf cart makes it very UNstable. It is top heavy. When I push up hill it will not hold its position. It also makes the cart (Sun Mountain reasonably heavy push cart) more apt to tilt or fall as you go over a hill.
I use my umbrella for shade in the sun, but if there is any wind, this product will not hold. I thought with the lock down for the umbrella, it would be good, but the directional tilt is very unstable & will start stripping.
