This accessory for the new Powakaddy range is not very well designed or built.
Design-wise, the only fitment position is on the top of the handle, therefore this puts the umbrella holder, when folded, directly behind, and in the way of, any golf club heads stored in the bottom of any attached golf bag, even when using Powakaddy's own cart bags. This means you either need to reorganise your clubs to avoid the bottom most position, or put up with wrestling clubs in/out each time you use one from that position. It is as if Powakaddy hadn't foreseen that people using this accessory on the CT6 may actually put clubs in their golf bag, noting gravity ensure clubs fall to the lowest position, which is then behind the holder when not in use!!
Build-wise, even when in use it seems impossible to get sufficient tightness on the screw mechanism to stop the holder, with an umbrella inside, from swaying around. This is more than just the flex of the plastic due to the weight of an umbrella, you can actually see the bracket has movement too meaning the side plates haven't nipped the holder tightly enough. Also any thin handled umbrellas have even more pitch and roll due to the design of the tube into which the umbrella is placed. Overall very poor.
