Overall, super. It does keep me protected from UV rays and substantially cooler in the summer sun. I am very pleased about its heft & versatility for use in rain! There are couple qualifying points that I'd like to make-
1. For the purpose of using this as a golf umbrella, attached to a walking pull cart, motorized or manual, I think the handle needs an upgrade as the butt end is a little flimsy when holding the umbrella in big gusts, trying to separate from the vise in the umbrella holder
2. The venting canopy in the center
Doesn't seem to catch much of a breeze when attached to my motorized cart
but to be fair, it's difficult to achieve breeze catching and structural integrity
3. Finally, it would be nice if it had a couple of holes, grommets or eye screws integrated at each end, in order to attach a strap so to make it harder to leave behind when one has their hands full!
