I got a great deal on this. It was only for this teal color but according to my research 16 ft by 16 ft triangles like this basically in any other place online are upwards of $200 and I got this 16x16 foot teal triangle sun sail for only like 55 bucks I think. It would be nice if it came with an installation kit but they sell them for like 30 bucks on Amazon, in all kinds of different versions depending on how you think you're going to want to hang yours and whether or not it's a triangle or a square or you're hanging multiple sails etc. You definitely have to hang it, then leave it in the weather for at least a week - let it get rained on, let it get some sun, let it naturally stretch itself out from being crumpled and bent in the packaging - and then after a week or so has gone by, go back to each of the corners, untighten and retighten them to get it pulled as tight as it really can go once it's fully stretched out. The only negative thing I have to say about it is that I expected it to be a perfectly even symmetrical triangle and it is not. I actually turned it all three positions it could go in in the space I was putting it to prove to myself that it really would need the hangers in different places depending on which way I spun it. If it were really a perfectly even symmetrical triangle it wouldn't matter which way I turned it, it would look exactly the same and the hangers would go in the same place now matter which way it was turned and that's not the case here. It had a totally different direction to it's reach depending on which way I turned it.
