I have experience with mine, But there is many makers of those things. Ours slides into a zipper and that slides into the notch of awning tube. Which I have to stand on up side bucket to get it started, and I'm 6 ft 3 in. But that is because our elec awning tube doesn't come down as far as our old manual. And I don't stake mine to ground. I like little bungee cord in the handle of two 3 gal water bottles. One at each end. Bungee cords give it more flexibility and more protection from wind gusts that are absorbed into bungee cords, and not straining the actual shade or awning. That is up to a certain point. When it's time to roll up the awning also we put up sun shade. As awning will not roll up with sun shade on it. (Someone said on here some time ago that there is one that does roll up with awning, but I've not seen it). Real easy to clean also, just hose off. I don't like folding it up to put it away though. 16 feet long and about 8 ft wide. Leaving us 1 foot at each end to dry out swim suites or bird feeder etc. Came with a carrying case about size of pillow case. I think it is one of these at bottom of page.
