The reason I bought this phone holder is because it's made by Clicgear and I assumed it was designed specifically for their golf carts. I'm sure I could've found a universal holder that works as well, maybe better in some ways, but after looking at the pictures in the listing I felt confident it would be less likely to interfere with other features of my cart. I did buy an additional phone case because the plastic installation tabs use adhesive tape. If you don't mind having a silver dollar size plastic button on the back of your phone case a second case isn't needed but the instructions do recommended using a case instead of attaching the tab directly to your phone. When clipped into the holder my phone seems quite secure. The holder has rubber cushions that can be adjusted to help keep your phone from spinning. This holder is attached to the cart using the same mount threads on the cart handle as the umbrella holder. The umbrella holder holds the phone holder in place when installed. I would suggest being gentle with this holder as the plastic parts used to clip in and release your phone look like they could be a little flimsy. All in all, I like this holder and it works as expected.
