Review on 2-Pack Durable Beach Umbrella Hanging Hooks - 4 Prongs For Towels, Hats, Clothes & More! by Billy Reeves

This is a strange looking piece that fits at the junction of your beach umbrella to hang your personal items. We hung our beach towels on it but they were dragging in the sand and the wind was whipping them around so, I don't recommend it for towel use, especially if you are sitting under the umbrella. Hanging things up under the umbrella also disrupted our view so, I believe this would be more useful when hanging smaller items. After affixing it to the umbrella, It tightens by turning a good sized knob. The strength of it "staying up" is dependent on how tightly you are able to fasten it.
