I already had the original Umbrella holder which wasn't adjustable and thought the newer version would be more helpful during play in the rain. I had an opportunity to use this recently and found it much better as I was able to adjust the umbrella according to the direction of the rain. Also, it raises the umbrella up a little higher, making it easier to see while walking and pushing the cart.
The one draw back I found was that the newer version (w/ Angle Adjuster) doesn't stay as secure in the umbrella holder or bracket that is fixed to the Click Gear Cart while not in use. It fits in the bracket fine, but the added weight of the base (from the Angle Adjustment) tends to make the holder fall off the Click Gear Cart if you are walking too fast and hit a bump. Other than that, this is a very good and well designed product.
