Works great so far.  I've only used it a couple times.  Perfectly replaces an old similar size umbrella I had that developed holes in the canopy.  I don't know that I'd call it "golf size", but it is a canopy that could be sized for two persons, or it's a generous size for one person.  At the same time, it folds down almost as much as my other totes with the smaller canopy.  Glad it was available in lovely, light blue!

The handle is fully covered in rubber-like material, so it's very grippy.  The open-close mechanism operates smoothly.  Measures 50" diameter straight across from spoke tip to spoke tip.  Measures 47" diameter straight across from flat side panel to flat side panel.  "Canopy" measurement, I feel, is somewhat irrelevant, as long as you have the straight-across diameter measure(s).
